This is in addition to the existing keystrokes r, ^R and ^Y. I've
become used to Ctrl-Shift-Z in other GUI games, and my fingers keep
getting confused when my own puzzles don't handle it the same way.

This fixes an amusing UI bug that I think can currently only come up
in the unpublished puzzle 'Group', but there's no reason why other
puzzles _couldn't_ do the thing that triggers the bug, if they wanted
to.
Group has unusual keyboard handling, in that sometimes (when a cell is
selected for input and the key in question is valid for the current
puzzle size) the game's interpret_move function will eat keystrokes
like 'n' and 'u' that would otherwise trigger special UI events like
New Game or Undo.
The bug is that fake keypress events generated from the GUI menus
looked enough like those keystrokes that interpret_move would eat
those too. So if you start, say, a 16x16 Group puzzle, select an empty
cell, and then choose 'new game' from the menu, Group will enter 'n'
into the cell instead of starting a new game!
I've fixed this by inventing a new set of special keystroke values
called things like UI_NEWGAME and UI_UNDO, and having the GUI menus in
all my front ends generate those in place of 'n' and 'u'. So now the
midend can tell the difference between 'n' on the keyboard and New
Game from the menu, and so Group can treat them differently too. In
fact, out of sheer overcaution, midend.c will spot keystrokes in this
range and not even _pass_ them to the game back end, so Group
shouldn't be able to override these special events even by mistake.
One fiddly consequence is that in gtk.c I've had to rethink the menu
accelerator system. I was adding visible menu accelerators to a few
menu items, so that (for example) 'U' and 'R' showed up to the right
of Undo and Redo in the menu. Of course this had the side effect of
making them real functioning accelerators from GTK's point of view,
which activate the menu item in the same way as usual, causing it to
send whatever keystroke the menu item generates. In other words,
whenever I entered 'n' into a cell in a large Group game, this was the
route followed by even a normal 'n' originated from a real keystroke -
it activated the New Game menu item by mistake, which would then send
'n' by mistake instead of starting a new game!
Those mistakes cancelled each other out, but now I've fixed the
latter, I've had to fix the former too or else the GTK front end would
now undo all of this good work, by _always_ translating 'n' on the
keyboard to UI_NEWGAME, even if the puzzle would have wanted to treat
a real press of 'n' differently. So I've fixed _that_ in turn by
putting those menu accelerators in a GtkAccelGroup that is never
actually enabled on the main window, so the accelerator keys will be
displayed in the menu but not processed by GTK's keyboard handling.
(Also, while I was redoing this code, I've removed the logic in
add_menu_item_with_key that reverse-engineered an ASCII value into
Control and Shift modifiers plus a base key, because the only
arguments to that function were fixed at compile time anyway so it's
easier to just write the results of that conversion directly into the
call sites; and I've added the GTK_ACCEL_LOCKED flag, in recognition
of the fact that _because_ these accelerators are processed by a weird
mechanism, they cannot be dynamically reconfigured by users and
actually work afterwards.)

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.

Use the puzzle background colour, like the GTK front end does.
(I know that renders the effect of the previous commit invisible,
but it's the principle of the thing! :-)

width and height by assuming mirror symmetry within the containing
applet area. Instead, use the proper width and height as given back
by the C sizing function.
(In particular, this fixes a bug where the non-blanked puzzle area
appeared too tall by the height of the menu bar, probably as a
result of confusing PuzzleApplet.getHeight() with
PuzzlePanel.getHeight(). But the mirroring approach was conceptually
wrong anyway.)

new function in the drawing API which permits the display of text
from outside basic ASCII. A fallback mechanism is provided so that
puzzles can give a list of strings they'd like to display in order
of preference and the system will return the best one it can manage;
puzzles are required to cope with ASCII-only front ends.

ALIGN_VNORMAL is in use: ALIGN_VNORMAL indicates that the supplied
y-coordinate denotes the _baseline_ of the text, not its top, so
adding on 'asc' to convert to the baseline is wrong.
This only affects Tents, at present.

argv[1], which in turn feeds it into the midend as a game ID. This
can of course take any of the forms supported by the native C
puzzles: a pure game parameter string, a params:description specific
game ID, or a params#seed random game ID.

to resize the puzzle to zero size. Ignore all such requests, in the
assumption that a more sensible resize will be along soon enough
(which does seem to happen, though I haven't debugged the NestedVM
front end hard enough to figure out why the bogus resizes happen in
the first place).
