Also fixed bug 3978 (Many Bonobo warnings/errors on quit).

	* libnautilus-extensions/nautilus-directory-async.c:
	(set_up_request_by_file_attributes),
	(update_file_info_in_list_if_needed),
	(dequeue_pending_idle_callback), (request_is_satisfied),
	(get_info_callback), (file_info_start):

	* libnautilus-extensions/nautilus-file-attributes.h:
	* libnautilus-extensions/nautilus-file-private.h:
	* libnautilus-extensions/nautilus-file.c:
	(nautilus_file_new_from_info), (destroy),

	(nautilus_file_compare_by_type),

	(nautilus_mime_set_short_list_applications_for_file),
	(nautilus_mime_set_short_list_components_for_file):
	Get rid of the distinction between slow and default MIME type once
	again. We (Pavel, Maciej, John, and I) decided it's better not to
	have multiple opinions on the MIME type, despite our original idea
	that we needed the slow MIME type for some things, even on remote
	file systems.

	* libnautilus-extensions/nautilus-glib-extensions.h:
	Fixed the formatting in this file.

	* src/file-manager/fm-directory-view.c: (load_location_callback):
	Only force a reload if we are reloading the same directory. This
	is needed to take advantage of the loading already done for us by
	the framework.
	(load_directory): Take a NautilusDirectory instead of a URI string.
	Also take a boolean parameter to control if we force a reload.
	(finish_loading_uri): Respect the boolean parameter that tells us
	whether to force a reload.
	(filtering_changed_callback): Use the new load_directory.

	* src/nautilus-applicable-views.c: (nautilus_navigation_info_new),
	(nautilus_navigation_info_cancel), (nautilus_navigation_info_free):
	Monitor the directory while we are loading the component. We
	already need to load the directory to get the MIME types, so this
	does no additional harm, and it prepares us to consolidate the
	loading done for different reasons.

	* src/nautilus-main.c: (main): Use nautilus_setenv instead of
	putenv, since it's more portable.

	* src/nautilus-window-manage-views.c: Quick simplification pass on
	state machine. Got rid of the use of varargs and renamed a bunch
	of things.

	* src/nautilus-window-manage-views.h:
	* src/nautilus-window-private.h:
	Moved external functions from nautilus-window-manage-views.c to
	all be in nautilus-window-manager-views.h. This is one step in
	reducing the number of clients that need access to private stuff
	in NautilusWindow.

	* src/nautilus-window-service-ui.c: (detach_service_ui),
	(nautilus_window_install_service_ui): Detach the service UI on
	"destroy" rather that using set_data_full, because finalize time
	is too late.

	* src/nautilus-view-frame.c: (nautilus_view_frame_destroy):
	Got rid of extra unref that was messing things up here.
