Add in the new InstantMessageService, which handles all conference IMs across the grid (including user to user conferences and group chat conferences). Properly implement all sending of conference messages and moderation features (minus voice chat integration). Remove all the attempts to do conferences locally and move it all to the new InstantMessageService which runs on the grid server and takes care of all of the message sending and moderation. Merge together group and user conferences, which were previously separate, even though they are the same thing.
