		add an extra constructor to restart an infinite session and
		return the SessionInfo on GetSession if it's an infinite one
	* src/Mono.Facebook/Responses:
		add the expires attribute on SessionInfo so we can check for
		infinite sessions and add an extra constructor to restore the
		infinite session
