- XSLTify the multimedia pages with a slightly different approach than the

earlier one.  It does not any more has per-tag and per-source pages
  but one page for tags and one for sources with anchors.  With the current
  number of entries it will probably be fine for a long time but if once
  we need to divide it into smaller chunks, it will be easier with XSLT.
- Now the documents are also rebuilt if stylesheets or the source XML
  database changes and the build time is drastically decreased.
