In other front ends, Shift-click is an alternative to the middle
button, and Ctrl-click the right button. Apparently I completely
forgot to implement this in the JS front end. Better late than never.

This is done by showing a dialog containing an <input type="file">
through which the user can 'upload' a save file - though, of course,
the 'upload' doesn't go to any HTTP server, but only into the mind of
the Javascript running in the same browser.
It would be even nicer to support drag-and-drop as an alternative UI
for getting the save file into the browser, but that isn't critical to
getting the first version of this feature out of the door.

This is done by getting midend_serialise to produce the complete
saved-game file as an in-memory string buffer, and then encoding that
into a data: URI which we provide to the user as a hyperlink in a
dialog box. The hyperlink has the 'download' attribute, which means
clicking on it should automatically offer to save the file, and also
lets me specify a not-too-silly default file name.

I'm about to want to call these from Javascript as well as from
Emscripten-compiled C, so I need versions of them that aren't wrapped
up in the Emscripten library object and also don't expect half their
parameters to be Emscripten-verse char pointers requiring calls to
Pointer_stringify.
The easiest way to achieve all of that is to turn the Emscripten-
ready versions of those functions in emcclib.js into tiny wrappers
around the JS versions, which do the pointer stringification and a
couple of other details like directing callbacks to the right C
functions.

To do this, I've completely replaced the API between mid-end and front
end, so any downstream front end maintainers will have to do some
rewriting of their own (sorry). I've done the necessary work in all
five of the front ends I keep in-tree here - Windows, GTK, OS X,
Javascript/Emscripten, and Java/NestedVM - and I've done it in various
different styles (as each front end found most convenient), so that
should provide a variety of sample code to show downstreams how, if
they should need it.
I've left in the old puzzle back-end API function to return a flat
list of presets, so for the moment, all the puzzle backends are
unchanged apart from an extra null pointer appearing in their
top-level game structure. In a future commit I'll actually use the new
feature in a puzzle; perhaps in the further future it might make sense
to migrate all the puzzles to the new API and stop providing back ends
with two alternative ways of doing things, but this seemed like enough
upheaval for one day.

The previous control buttons and dropdowns based on form elements were
always a bit ugly: partly in a purely visual sense, and partly because
of the nasty bodge I had to do with splitting the usual 'Custom' game
type menu item into two (to get round the fact that if an element of a
<select> is already selected, browsers won't send an event when it's
re-selected). Also, I'm about to want to introduce hierarchical
submenus in the Type menu, and <select> doesn't support that at all.
So here's a replacement system which does everything by CSS
properties, including the popping-up of menus when the mouse moves
over their parent menu item. (Thanks to the Internet in general for
showing me how that trick is done.)

The mouseup listener was calling event.preventDefault(), as part of
the mechanism for making mouse clicks and drags on the puzzle's resize
handle have resizing effects _instead_ of the normal browser
behaviour. However, calling event.preventDefault() on _every_ mouseup,
rather than just the ones associated with the resize handle, was
overkill, and I've recently noticed that it's breaking attempts to
select from the game type dropdown by clicking the mouse. So now I'm
only calling preventDefault() on the mouseups that I have reason to
think are actually relevant to what I'm trying to do.
(I don't know why I've only just noticed this. I suppose a change of
behaviour between Firefox versions is the most likely cause.)

I've just upgraded to emcc 1.16.0, in which something fiddly has
happened to the semantics of Module.run() vs noInitialRun - now
setting the latter seems to cause the former to do everything except
calling main(), and then refuse to ever do anything again. So now I
have to use Module.callMain() in place of Module.run() when I finally
do get round to wanting to call main().

Rather than design an ersatz 'window frame' surrounding the puzzle
canvas, I've simply overlaid the resize handle on the corner of the
puzzle itself (canvas or status bar, depending on whether the latter
exists), trusting that all games in my collection provide a reasonable
border within their drawing area. (OS X already does this with its
resize handle, so it's not as if there's no precedent.)
Unlike the desktop versions, I control the resize behaviour completely
in this environment, so I can constrain the canvas to only ever be
sensible sizes with no dead space round the edges (and, in particular,
preserve the aspect ratio).
Right-clicking the resize handle will restore the puzzle's default
tile size. I had intended to implement a maximise-to-browser-window
button too, but was annoyingly foiled by scrollbars - if you maximise
to the current window width, and as a result the text below the puzzle
scrolls off the bottom, then a vertical scrollbar appears and eats
into the width you just maximised to. Gah.

the game-type <select>, since IE turns out to ignore display:none on
options. Oh well.
Instead I now do a more transparent thing: when custom game params are
in use, there's a "Custom" option selected in the dropdown, and a
separate 'Re-customise' option which brings the config box back up.
When an ordinary preset is selected, the Custom option is missing, and
there's just a 'Customise'.
In the process I've tinkered a bit to arrange that the custom 'preset'
is always represented by a negative number rather than one past the
last real preset; that seems more consistent overall.

Unlike Firefox, IE and Chrome don't generate keypress events at all if
you suppress the default handling of keydowns. Therefore, we have to
figure out everything from the keydown event, because if we unsuppress
the default handling of any keydowns then we'll get annoyances like ^R
going back to meaning reload-page rather than redo-move.

the return value of relative_mouse_coords! I only got away with that
error because the canvas was at offset zero compared to its immediate
parent element.

hard to focus the canvas at all in IE.)

didn't like them, which doesn't matter as such since they won't run
these JS puzzles anyway (no TypedArray support) but it hints that
other JS implementations might be picky about this too.

mention that the HTML pages generated by html/jspage.pl are also an
integral part of this front end. (The NestedVM frontend is more
self-contained, needing only an appropriate <applet> tag, but this one
expects quite a few components to exist on the page and have the right
ids.)

puzzle startup. The puzzle web pages now enclose the whole puzzle
(buttons, canvas, permalinks) in a div set to display:none, and
instead display an apologetic message saying 'sorry, it didn't work';
then, if we get through the whole init function without crashing, we
show the puzzle and hide the apology.

type dropdown, we still get an 'onchange' event if they select it a
second time. Normally this wouldn't happen, because onchange means
what it says and we only get it if a _different_ element is selected.
My solution is to create two list items called Custom, set one of them
as display:none to stop it showing up when the list is dropped down,
and to select it after the configuration box closes.

applets, here's an alternative webification in Javascript, using
Emscripten in asm.js mode (so that as browsers incorporate asm.js
optimisation, the game generation should run really fast).
