	Patch by: William Grant <wgrant ubuntu com>

	* plugins/mouse/gsd-mouse-manager.c: (devicepresence_filter),
	(set_devicepresence_handler), (set_mouse_settings),
	(gsd_mouse_manager_start), (gsd_mouse_manager_stop): listen for
	X device changes, and reconfigure the mouse if necessary so that the
	settings aren't ignored when hotplugging (bug #549267)
