* libnautilus-extensions/nautilus-directory.h,
	libnautilus-extensions/nautilus-directory.c:
	(nautilus_directory_wait_until_ready): Non-asynchronous equivalent
	of `nautilus_directory_call_when_ready'. However, it doesn't block
	the UI while waiting.
	(nautilus_directory_wait_until_ready_callback): Helper function
	for implementing the above.

	* libnautilus-extensions/nautilus-mime-actions.c:
	(nautilus_mime_get_default_action_type_for_uri,
	nautilus_mime_get_default_action_for_uri,
	nautilus_mime_get_default_application_for_uri,
	nautilus_mime_get_default_component_for_uri): Implemented with
	fully with proper metadata checking and interface querying, etc.

	(nautilus_mime_get_short_list_applications_for_uri,
	nautilus_mime_get_short_list_components_for_uri,
	nautilus_mime_get_all_applications_for_uri,
	nautilus_mime_get_all_components_for_uri): Adjusted to deal with
	the mime type checking function changing names.

	(OAF_ServerInfo__copy, extract_prefix_add_suffix,
	mime_type_get_supertype, uri_string_get_scheme),
	get_explicit_content_view_iids_from_metafile,
	make_oaf_query_for_explicit_content_view_iids,
	make_oaf_query_with_known_mime_type,
	make_oaf_query_with_uri_scheme_only,
	file_list_to_mime_type_hash_table, free_key,
	mime_type_hash_table_destroy, server_matches_content_requirements,
	nautilus_do_component_query): Oodles of helper functions, many cut
	& pasted from elswhere and only slightly modified.
	get_mime_type_from_uri: Removed `_hack' from the name.

	* libnautilus-extensions/nautilus-mime-actions.h: Added prototype
	for nautilus_mime_get_default_action_type_for_uri.

	* test/test-nautilus-mime-actions.c (main): Call gnome_init.

	* src/nautilus-applicable-views.c: Removed a stray comment that no
	longer applies.
