Spice up setstyle
- convert to getopt
- tidy xsendevent
- modify hackPathInTexture() so that:
- it properly figures where the style file is
- if it's under the user's home directory, that part of the path
is changed to `~' - this makes your wm configuration usable on
systems with a network home, used on systems where home is /home,
or /u, or /export/home, or whatever.
XXX: there's a note WINGs/findfile.c:wexpandpath() stating that
`too many functions handle a return value of NULL incorrectly'. this is
so true. so if anyone is looking for a small project to sink their
teeth in...
