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.

+Bridges
+<p>
+Draw horizontal or vertical bridges to link up all the islands.
+Bridges may be single or double; they may not cross; the islands
+must all end up connected to each other; the number in each island
+must match the number of bridges that end at that island (counting
+double bridges as two). Note that loops of bridges are permitted.
+<p>
+Click on an island and drag left, right, up or down to draw a bridge
+to the next island in that direction. Do the same again to create a
+double bridge, and again to remove the bridge if you change your
+mind. Click on an island without dragging to mark the island as
+completed once you think you have placed all its bridges.
