Updated test user scripts to send a movement event when they join a room so that the server can know their last position. Added 'roomlist' method that clients can call to receive a list of all rooms and the users inside them where the users do not have 'doNotTrack' set to TRUE in their sessions. When users login to the server they can set a doNotTrack flag which stops the server from storing their position and returning the user in the list of users in the room that the user is in.
