Misc. blosxom fixes, like category directive.
* contrib/pyblosxom/getstamps.py: Add file extension.
* contrib/pyblosxom/hardcodedates.py (get_all_timestamps): Omit file
extension. This will allow Muse to specify it once a
timestamps-writing routine gets written.
* lisp/muse-blosxom.el (muse-blosxom-update-page-date-alist): Pay
attention to the "category" directive, if it exists. Use file-truename
instead of expand-file-name for base directory.
* lisp/muse-blosxom.el (muse-blosxom-new-entry): Add #category directive
by default.
* lisp/muse-project.el (muse-project): Add :timestamps to list of
available tags, even though it doesn't do anything yet.
