Allow bad WikiWords to be colorized, by popular request.
* lisp/muse-colors.el (muse-link-face): Allow implicit links to be
colored as bad links if they don't correspond with a real file. Make
the code more straightforward.
* lisp/muse-wiki.el (muse-wiki-ignore-bare-project-names): New option
that determines whether to colorize nonexistent WikiWords. The default
is nil, which means "don't colorize".
(muse-wiki-resolve-project-page, muse-wiki-handle-wikiword): Adapt for
the possibility of bad WikiWords.
