Attempt to get the right file extension when publishing; more examples.

* examples/mwolson/muse-init.el: Update my configuration.

* examples/mwolson/templates: Store my web page templates here.

* examples/mwolson/stylesheets: Store my CSS stylesheets here.

* lisp/muse-publish.el (muse-publish-markup-link): Fix mangling of
  descriptions.  Yet another reason to implement my list-returning from
  handlers idea.

* lisp/muse-wiki.el (muse-wiki-resolve-project-page): Deal gracefully
  with a few more edge cases.  Throw together a rough hack for
  determining when to include the output file extension.

* lisp/muse-wiki.el (muse-wiki-colors-nop-tag): Make this less odious,
  but still ineffective.
