Finish documenting 2 more publishing styles.
* lisp/muse-blosxom.el, lisp/muse-latex.el: Minor docfixes throughout.
* lisp/muse-journal.el: Docfixes.
* lisp/muse-publish.el (muse-publish-markup-functions): Add significant
documentation to this function.
* muse.texi (Blosxom Options): New node containing the publishing styles
and options provided by Blosxom.
(Book): Add usage note, as I suspect a lot of people might be confused
by this style.
(HTML): Space out entries better.
(Journal, LaTeX): New nodes for publishing styles.
(Common Elements): Document a few options that are present in
`muse-publish.el'.
