Get Ikiwiki stuff working minimally.
* examples/ikiwiki/IkiWiki/Plugin/muse.pm: Move here from
examples/ikiwiki/muse. Encode/decode UTF-8 properly. Take pains to
remove the temp file. Die on errors. Remove test sub.
* examples/ikiwiki/muse-init-project.el: Remove server stuff.
* lisp/muse-ikiwiki.el (muse-ikiwiki-publish-file): Set font-lock-verbose
to nil to avoid spurious messages when publishing. Silence the "Wrote
file" message.
* lisp/muse-publish.el (muse-batch-publish-files): Set font-lock-verbose
to nil to avoid spurious messages when publishing.
* lisp/muse.el (muse-write-file): Take NOMESSAGE argument.
* texi/muse.texi (Ikiwiki): Add instructions for using
IkiWiki::Plugin::muse.
