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.
