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.

+Netslide
+<p>
+Slide the grid squares around so that they all join up into a single
+connected network with no loops.
+<p>
+Click on the arrows at the edges of the grid to move a row or column
+left, right, up or down. The square that falls off the end of the
+row comes back on the other end.
+<p>
+Squares connected to the middle square are lit up. Aim to light up
+every square in the grid (not just the endpoint blobs).
+<p>
+Connecting across a red barrier line is forbidden. On harder levels,
+there are fewer barriers, which makes it harder rather than easier!
