Overhauled the docs.  Removed all the HTML files, put in XML files as
converted by Donna.  Hooked it into the build system so they are only
built when specifically asked for, and when doing "make dist".

They're not perfect;  in particular, there are the following problems:
- The plain-text FAQ should be built from FAQ.xml, but this is not
  currently done.  (The text FAQ has been left in for now.)

- The PS/PDF building doesn't work -- it fails with an incomprehensible
  error message which I haven't yet deciphered.

Nonetheless, I'm putting it in so others can see it.
