Rewrite Ruleset to hide Webinar Mode from URL

This should give you a hint howto hide the special page anchor used to start the client in Webinar Mode from the URL used to invite users to an event.

The following is a snippet from a virtual host configuration used for the the vhost meet.example.com. This is also used as a landing page (taken from index.hml). The Openfire server with the OpenMeet plugin is running at the domain xmpp.example.com; the OpenMeet plugin's context path is configured to use / (!)

Conference rooms are accessed for the moderator and members by

   https://meet.example.com/room/<name>

and for listeners by

   https://meet.example.com/hall/<name>
