Finished moving classes out from include/reddav.php into own files. Also
continued with namespace for RedDAV.
Improved some docs and added some todos and fixmes.
First step on cleaning up ReadDAV classes and restructuring it bit in
preparation for adding some more DAV features, photo access, CalDAV, etc.
and hopefully also some PHPunits.
Add a PHP5.3 namespace for RedDAV classes. Any objections against this or
the vendor namespace?
Add some more documentation for RedBrowser.
