puzzles: refactor and resync with upstream

This brings puzzles up-to-date with upstream revision
2d333750272c3967cfd5cd3677572cddeaad5932, though certain changes made
by me, including cursor-only Untangle and some compilation fixes
remain. Upstream code has been moved to its separate subdirectory and
future syncs can be done by simply copying over the new sources.

+Same Game
+<p>
+Try to empty the playing area completely, by removing connected
+groups of two or more squares of the same colour. Then try to score
+as much as possible, by removing large groups at a time instead of
+small ones.
+<p>
+Click on a coloured square to highlight the rest of its connected
+group. The status line will print the number of squares selected,
+and the score you would gain by removing them. Click again to remove
+the group; other squares will fall down to fill the space, and if
+you empty a whole column then the other columns will move up. You
+cannot remove a single isolated square: try to avoid dead-end
+positions where all remaining squares are isolated.
