When a conference is created, the UNIQUEID of the channel that caused it to be

created will now be stored. Then, every channel that joins the conference will
have the MEETMEUNIQUEID channel variable set with this ID.  This can be used to
relate callers that come and go from long standing conferences.
(issue #7295, patch by softins)
