Port of Simon Tatham's Puzzle Collection

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.

Currently builds one plugin per puzzle (about 40 in total, around 100K
each on ARM), but can easily be made to build a single monolithic
overlay (800K or so on ARM).

The following games are at least partially broken for various reasons,
and have been disabled on this commit:

Cube:     failed assertion with "Icosahedron" setting
Keen:     input issues
Mines:    weird stuff happens on target
Palisade: input issues
Solo:     input issues, occasional crash on target
Towers:   input issues
Undead:   input issues
Unequal:  input and drawing issues (concave polys)
Untangle: input issues

Features left to do:
 - In-game help system
 - Figure out the weird bugs

+Towers
+<p>
+Fill in the grid with towers whose heights range from 1 to the grid
+size, so that every possible height appears exactly once in each row
+and column, and so that each clue around the edge counts the number
+of towers that are visible when looking into the grid from that
+direction. (Taller towers hide shorter ones behind them. So the
+sequence 2,1,4,3,5 would match a clue of 3 on the left, because the
+1 is hidden behind the 2 and the 3 is hidden behind the 4. On the
+right, it would match a clue of 1 because the 5 hides everything
+else.)
+<p>
+To place a tower, click in a square to select it, then type the
+desired height on the keyboard. To erase a tower, click to select a
+square and then press Backspace.
+<p>
+Right-click in a square and then type a number to add or remove the
+number as a pencil mark, indicating tower heights that you think
+<em>might</em> go in that square.
+<p>
+Left-click on a clue to mark it as done (grey it out). To unmark a
+clue as done, left-click on it again.
