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.

+Map
+<p>
+Colour the map with four colours, so that no two adjacent regions
+have the same colour. (Regions touching at only one corner do not
+count as adjacent.) There is a unique colouring consistent with the
+coloured regions you are already given.
+<p>
+Drag from a coloured region to a blank one to colour the latter the
+same colour as the former. Drag from outside the grid into a region
+to erase its colour. (You cannot change the colours of the regions
+you are given at the start of the game.)
+<p>
+Right-drag from a coloured region to a blank one to add dots marking
+the latter region as <em>possibly</em> the same colour as the
+former, or to remove those dots again.
