[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.
