xfce: startup script.

Historically, I had a .xinitrc file that I used to launch all of the
windowing environment stuff that I wanted.  It was a complex and
confusing shell script, and after 20 years, it was full of outdated
cruft that tried to track what distributions now generally do for
you.

So, instead, I've taken over the stuff that truly is personal to me
and put it into this xfce autostart script.
