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.

-Rotate square sections of the grid to arrange the squares into
-numerical order starting from the top left.
-<p>
-In the basic game, you rotate a 2&times;2 square section. Left-click
-in the centre of that section (i.e. on a corner point between four
-squares) to rotate the whole section anticlockwise. Right-click to
-rotate the section clockwise.
-<p>
-When you master the basic game, go to the Type menu to try it with
-larger rotating groups (for a 3&times;3 group you must click in the
-centre of a square to rotate the block around it). Or select the
-'orientable' mode in which every square must end up the right way
-round as well as in the right place. Or both!
