		/**
		 * Joins a conference room based on the parameters specified by the room
		 * properties.	This call will create an instant room based on a default
		 * server configuration if the room doesn't exist.
		 *
		 * <p>To create and begin the configuration process of a reserved room, pass
		 * <code>true</code> to this method to begin the configuration process.	When
		 * The configuration is complete, the room will be unlocked for others to join.
		 * Listen for the <code>RoomEvent.CONFIGURE_ROOM</code> event to handle and
		 * either return or cancel the configuration of the room.
		 *
		 * This function adds an additional parameter to allow the caller to completely customize the MUC extension that 
		 * gets sent to the room.  For example, you can add a history element that specifies how much discussion
		 * history you want sent when you join the room (http://xmpp.org/extensions/xep-0045.html#enter-managehistory):
		 * <code>
		 * var muc:MUCExtension = new MUCExtension();
		 * muc.history = true;
		 * muc.maxchars = 0;
		 * _room.joinWithExplicitMUCExtension(false, mucExt);
		 * </code>
		 * 
		 * @param	createReserved Set to true if you wish to create and configure a reserved room
		 * @param	mucExtension The customized MUC extension to send with initial presence to the room.
		 * @param	joinPresenceExtensions An array of additional extensions to send with the initial presence to the room.
		 * @return A boolean indicating whether the join attempt was successfully sent.
