Fill in string, length and is_modifier for key events. Map some more keys

2006-07-17  Richard Hult  <richard@imendio.com>

	* gdk/quartz/gdkevents-quartz.c: (create_key_event):
	* gdk/quartz/gdkkeys-quartz.c: (_gdk_quartz_key_event_type),
	(_gdk_quartz_key_is_modifier):
	* gdk/quartz/gdkprivate-quartz.h: Fill in string, length and
	is_modifier for key events. Map some more keys into gdk keyvals.
