Grouped functions working in livedocs

Cheers, Today with good cooperation from the guys on phpdoc#, we made the grouped function listing (RFC/manual.xml.in) work in livedocs. With introducing a simple new grouping tag, this change needs our own DTD (which is based on DocBook), but I beleive it is worth this small change. Check out the grouping on the unofficial livedocs site here: http://livedocs.phpdoc.info/index.php?l=en&q=manual Now it would be nice to discuss two things: - whether these categories are fine - whether the reference sections are categorized in the right

    places or not

After we finalize the categorization, we can put the category names to entities, so they will work with translated manuals too. Now this is another reason to use (and work on soon switching to) livedocs. Goba
