Gnome updates (from <Someone> <Someone> Simon)

- fix destruction of primary game windows
- One, it makes the color of the cursor box dynamic (these are the gnmap.c
changes), based on hp/hpmax (continuous colors white -> yellow -> red ->
magenta rather than discrete like in Qt).
- Two, it adds a new window, NHW_WORN (all the other changes and new files
gnworn.[ch]), placed at the end of the first row, to the right of the status,
with tiles of all the items currently equiped.  I had to change the spacing of
the first row (no longer homogeneous) to accomodate this, but I think it still
looks okay.  It's mostly like the Qt version but the equiped items are in
slightly different places, and a bit more compactly (added quiver, ball/chain,
monster skin armor; see the definition in gnworn.c for the layout).
