* libnautilus-extensions/nautilus-global-preferences.c:
	(global_preferences_get_dialog),
	(global_preferences_register_for_ui),
	(nautilus_global_preferences_dialog_update),
	(nautilus_global_preferences_initialize):
	* libnautilus-extensions/nautilus-global-preferences.h:

	Expose the initialization call once again.  I suppose explicit
	initialzation was a dream.  It seems to break everytime we add
	something new at startup that needs preferences, so lets just make
	sure preferences defaults exist once and for all.

	* src/nautilus-application.c: (nautilus_application_initialize),
	(nautilus_application_destroy), (nautilus_application_startup),
	(check_for_and_run_as_super_user), (need_to_show_first_time_druid):

	Change the way we check whether the first time wizrard needs to be
	presented.  Instead of checking for the user's 'top' directory, we
	check a flag file: ~/.nautilus/first-time-wizard.

	Checking the user's top directory doesnt work after my last
	preferences changes, since the preferences initialization call i
	added causes the 'top' directory to exist and this confuses the
	first time druid.
