* libnautilus-extensions/Makefile.am:
	* libnautilus-extensions/nautilus-preferences-private.h:
	Remove unused header.

	* libnautilus-extensions/nautilus-directory.c:
	(nautilus_directory_get_internal):
	Remove unnecessary removal of preferences callbacks at exit time.
	This happens automatically.

	* libnautilus-extensions/nautilus-gconf-extensions.h:
	* libnautilus-extensions/nautilus-gconf-extensions.c:
	(nautilus_gconf_client_get_global), (nautilus_gconf_set_integer),
	(nautilus_gconf_get_integer), (nautilus_gconf_is_default),
	(nautilus_gconf_monitor_add), (nautilus_gconf_monitor_remove),
	(nautilus_gconf_value_free), (nautilus_gconf_notification_add),
	(nautilus_gconf_notification_remove):
	New functions for easier addition and removal of notifications.
	New funtions for easier addition and removal of directory
	monitoring.
	Add a #define for a undefined connection.

	* libnautilus-extensions/nautilus-global-preferences.h:
	Remove SOUND_STATE hack.

	* libnautilus-extensions/nautilus-sound.c:
	(kill_sound_if_necessary), (nautilus_sound_initialize),
	(nautilus_sound_kill_sound), (nautilus_sound_register_sound),
	(nautilus_sound_can_play_sound):
	Use gconf directly for the sound state hack, since nautilus
	preferences arent really useful for this specific use because of
	initialization, and default value issues.

	* libnautilus-extensions/nautilus-global-preferences.c:
	(nautilus_global_preferences_initialize):
	Pass in the storage prefix when initializing preferences.

	* libnautilus-extensions/nautilus-preferences.h:
	We now need to pass in the storage prefix when initializing.

	* libnautilus-extensions/nautilus-preferences.c:
	Change the way preferences are initialized a little bit.  We now
	feed the initialize function a storage prefix to use for gconf.
	Add assertions for any public function that was used before
	initialization.  Make the key allocations a little faster by
	caching the prefixes that hardly ever change.  Simplify the
	addition and removal of gconf notifications by using the new gconf
	extensions to do so.
	Add a little bit of self checks.  I need to figure out a gconf
	problem before adding more checks, these are very minimal for now.
