- godoc now supports the following url prefixes:
  /doc/ for package documentation
  /file/ for files (directories, html, and .go files)
  /spec for the spec
  /mem for the memory model
- formatting of comments has been fixed
- tons of minor cleanups (still more to do)

Still missing:
- pretty printing of source is not as pretty as it used to be
(still a relict from the massive AST cleanup which has't quite made it's way everywhere)
- documentation entries should be sorted
- comments in code is not printed or not properly printed

first round of cleanups:
- removed extra .html templates (reduced to one)
- removed dependencies on various local files
- minor fixes throughout

(multi-file) packages under a root and serves either file
or package documentation.
