Also, after some testing, it turns out that my previous assumption about
systemd was wrong. Placing a service in default.target.wants directly
will cause the service to instead not be recognized by systemd.
"Desktop" was a really generic package name that didn't describe the
contents of what it contained. Since we already have a catch-all
directory (extras), I separated "desktop" into what it actually was:
settings for urxvt/termite and settings for xmodmap.
Some other programs may also use xrdb. The only reason the term files
are not in the bspwm directory instead is because it may be useful to
use urxvt or termite in non-bspwm environments.
