generation) from a simple but rather fun Flash game I saw this
morning.
Small infrastructure change for this puzzle: while most game
backends find the midend's assumption that Solve moves are never
animated to be a convenience absolving them of having to handle the
special case themselves, this one actually needs Solve to be
animated. Rather than break that convenience for the other puzzles,
I've introduced a flag bit (which I've shoved in mouse_priorities
for the moment, shamefully without changing its name).

generator. The generator is lacking in almost any kind of finesse,
but it produces puzzles which at least _I_ find plausibly puzzling.

introduces a few new utility functions in misc.c, one of which is
the bitmap obfuscator from Mines (which has therefore been moved out
of mines.c).

(solving it only requires matrix inversion over GF(2), whereas
several of the other puzzles in this collection are NP-complete in
principle), but it's a fun enough thing to play with and is
non-trivial to do in your head - especially on the hardest preset.

binary if we choose: fix bugs in cube.c and sixteen.c that manifest
when compiled that way, and introduce list.c which provides a global
list of all the available puzzles.
