- 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).
- change the way the tile sizes are calculated, based on the image size,
so non-square tiles can once again be supported.
- fix Gnome port so it can actually display non-square tiles, several
height/width uses were backwards
- update Install.X11 to note the number of tiles per row in the XPM image
