[WIP] Port of Simon Tatham's Puzzle Collectionpuzzles

Original revision: 5123b1bf68777ffa86e651f178046b26a87cf2d9

MIT Licensed. Some games still crash and others are unplayable due to
issues with controls. Still need a "real" polygon filling algorithm.

The following games are at least partially broken for various reasons:

Cube:     crash with certain settings
Galaxies: crash
Inertia:  crash
Keen:     input issues
Loopy:    weird stuff happens
Map:      crash on input
Mines:    weird stuff happens on target
Palisade: input issues
Signpost: crash on input
Solo:     input issues
Towers:   input and drawing issues
Train Tracks: drawing issues
Twiddle:  weird animation on target
Undead:   input and drawing issues
Unequal:  input and drawing issues
Untangle: input issues

All in all, about 40% of the games are at least partially broken.

+This is the README accompanying the source code to Simon Tatham's
+puzzle collection. The collection's web site is at
+<http://www.chiark.greenend.org.uk/~sgtatham/puzzles/>.
+
+If you've obtained the source code by downloading a .tar.gz archive
+from the Puzzles web site, you should find several Makefiles in the
+source code. However, if you've checked the source code out from the
+Puzzles git repository, you won't find the Makefiles: they're
+automatically generated by `mkfiles.pl', so run that to create them.
+
+The Makefiles include:
+
+ - `Makefile.am', together with the static `configure.ac', is intended
+   as input to automake. Run `mkauto.sh' to turn these into a
+   configure script and Makefile.in, after which you can then run
+   `./configure' to create an actual Unix Makefile.
+
+ - `Makefile.vc' should work under MS Visual C++ on Windows. Run
+   'nmake /f Makefile.vc' in a Visual Studio command prompt.
+
+ - `Makefile.cyg' should work under Cygwin / MinGW. With appropriate
+   tweaks and setting of TOOLPATH, it should work for both compiling
+   on Windows and cross-compiling on Unix.
+
+ - `Makefile.osx' should work under Mac OS X, provided the Xcode
+   tools are installed. It builds a single monolithic OS X
+   application capable of running any of the puzzles, or even more
+   than one of them at a time.
+
+ - `Makefile.wce' should work under MS eMbedded Visual C++ on
+   Windows and the Pocket PC SDK; it builds Pocket PC binaries.
+
+Many of these Makefiles build a program called `nullgame' in
+addition to the actual game binaries. This program doesn't do
+anything; it's just a template for people to start from when adding
+a new game to the collection, and it's compiled every time to ensure
+that it _does_ compile and link successfully (because otherwise it
+wouldn't be much use as a template). Once it's built, you can run it
+if you really want to (but it's very boring), and then you should
+ignore it.
+
+DO NOT EDIT THE MAKEFILES DIRECTLY, if you plan to send any changes
+back to the maintainer. The makefiles are generated automatically by
+the Perl script `mkfiles.pl' from the file `Recipe' and the various
+.R files. If you need to change the makefiles as part of a patch,
+you should change Recipe, *.R, and/or mkfiles.pl.
+
+The manual is provided in Windows Help format for the Windows build;
+in text format for anyone who needs it; and in HTML for the Mac OS X
+application and for the web site. It is generated from a Halibut
+source file (puzzles.but), which is the preferred form for
+modification. To generate the manual in other formats, rebuild it,
+or learn about Halibut, visit the Halibut website at
+<http://www.chiark.greenend.org.uk/~sgtatham/halibut/>.
