Subject: 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.

+# This is used in the Puzzles icon build scripts to construct icons
+# which are zoomed in on a particular sub-area of the puzzle's
+# basic screenshot. This way I can define crop areas in pixels,
+# while not having to worry too much that if I adjust the source
+# puzzle so as to alter the layout the crop area might start
+# hitting the wrong bit of picture. Most layout changes I can
+# conveniently imagine will also alter the overall image size, so
+# this script will give a build error and alert me to the fact that
+# I need to fiddle with the icon makefile.
