Merge branch 'media-revisions'

This introduces a new media manager and media revisions to DokuWiki. The
changes have been implemented by Kate Arzamastseva and are the
result of a Google Summer of Code project, the official project page can
be found at
http://www.google-melange.com/gsoc/project/google/gsoc2011/kate/18001

Thanks to Kate for the work and Google for sponsoring it!
