	Made session management multiscreen aware:

	* app/widgets/gimpsessioninfo.[ch]: added "gint screen" member
	to struct GimpSessionInfo.

	(gimp_session_info_get_geometry): ask the window for its screen.
	(gimp_session_info_restore): place the window on the remembered
	screen if the screen exists.

	(gimp_session_info_save)
	(gimp_session_info_deserialize): extended "open-on-exit" property
	to include the screen number (e.g. "(open-on-exit 1)" for screen 1).

	This change breaks everybody's sessionrc again...
