Doc's makefile work

* Clean up the makefile so that it
  can easily handle other asciidoc
  install locations and knows about
  LaTeX equations.

* Add new makefile target to build
  "external" html documentation. e.g.:

    make external-install TARGET="/web-directory"

* Don't bother keeping uneeded stuff
  around after make install (run make
  clean).

* If it isn't present, make a funcs
  dir.
