- support X11 tile files (with or without XPM) that are 40 tiles wide
- rearrange some X11 code to share more code between XPM & non-XPM options
- clean out some deprecated X11/winmap.c #ifdefs
- update Qt code minimally to handle such an XPM file
- Pat noticed that makedefs -z makes both vis_tab.[ch], but they could be
built by two makes via make -j, causing corruption
- make -j at top level failed for similar reasons, added several
dependencies to ensure a valid ordering
- these changes will cause extra things to be built if you "make"
individual targets at the top level, but have little effect it you're a
real power user and "make" the actual target in the right directory
