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.

+Black Box
+<p>
+Determine where the hidden balls are in the box, by observing the
+behaviour of light beams fired into the box from the sides.
+<p>
+Click in a square around the edge of the box to send a beam into the
+box. Possible results are 'H' (the beam hit a ball dead-on and
+stopped), 'R' (the beam was either reflected back the way it came or
+there was a ball just to one side of its entry point) or a number
+appearing in two squares (indicating that the beam entered one of
+those squares and emerged from the other).
+<p>
+Click in the middle of the box to place your guessed ball positions.
+When you have placed enough, a green button will appear in the top
+left; click that to indicate that you think you have the answer.
+You can also right-click to mark squares as definitely known.
