Rewrite Ruleset to hide Webinar Mode from URL

About

This should give you a hint howto hide the special page anchor #config.webinar=true used to start the client in Webinar Mode from the URL used to invite users to an event as an attendee.

The following is a snippet from a virtual host configuration used for the the vhost meet.example.com. This is used as the public domain to present the service. 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 / (!)

The URL scheme

The landing page with instructions or similar (taken from index.hml) is accessed at

	https://meet.example.com

One may use

	https://meet.example.com/room

to name a room for a meeting.

The direct stage door to the conference THE_NAME for the moderator and talk members is accessed (as usual) by

	https://meet.example.com/room/THE_NAME

The direct hall entry for the attendees to the conference THE_NAME is

	https://meet.example.com/hall/THE_NAME

and in an analogous way, a attendee may choose a hall at

	https://meet.example.com/hall
