Rather than each game backend file exporting a whole load of

functions and a couple of variables, now each one exports a single
structure containing a load of function pointers and said variables.
This should make it easy to support platforms on which it's sensible
to compile all the puzzles into a single monolithic application. The
two existing platforms are still one-binary-per-game.

  * windows.c: Windows front end for my puzzle collection.
+ * 
+ * TODO:
+ * 
+ *  - Figure out what to do if a puzzle requests a size bigger than
+ *    the screen will take. In principle we could put scrollbars in
+ *    the window, although that would be pretty horrid. Another
+ *    option is to detect in advance that this will be a problem -
+ *    we can probably tell this using midend_size() before actually
+ *    generating the puzzle - and simply refuse to do it.
