A cut at an ability to build without Medusa, starting with a patch
	that Eric Fischer wrote. This change is not fully tested.

	Fixed bug 5513 ("nautilus --help" displays "Help options" twice).

	* acconfig.h: Add HAVE_MEDUSA.
	* configure.in: Add code to detect HAVE_MEDUSA.

	* libnautilus-extensions/nautilus-customization-data.c:
	(nautilus_customization_data_destroy), (load_name_map_hash_table):
	Added a FIXME.

	* libnautilus-extensions/Makefile.am:
	* libnautilus-extensions/nautilus-file.h:
	* libnautilus-extensions/nautilus-trash-file.h:
	* libnautilus-extensions/nautilus-trash-file.c:
	(nautilus_trash_file_initialize), (trash_destroy),
	(nautilus_trash_file_initialize_class):
	* libnautilus-extensions/nautilus-vfs-file.h:
	* libnautilus-extensions/nautilus-vfs-file.c:
	(nautilus_vfs_file_initialize), (vfs_destroy),
	(nautilus_vfs_file_initialize_class):
	Initial cut at breaking out the special trash version of
	NautilusFile. Sadly we need this as well as
	NautilusTrashDirectory.

	* src/file-manager/fm-search-list-view.c:
	(load_location_callback): Add _() so things get localized and put
	the code to compose the indexing message inside ifdef HAVE_MEDUSA.

	* src/file-manager/nautilus-indexing-info.h:
	* src/file-manager/nautilus-indexing-info.c:
	Put HAVE_MEDUSA ifdefs around most of this file.
	(get_text_for_progress_label): Mark string for translation.
	(update_progress_display): Remove code to "handle" timeout left
	around after dialog is destroyed.
	(update_file_index_callback): Change error messages to be more
	easily localizable. Use nautilus_error_dialog instead of
	gnome_error_dialog.
	(timeout_remove_callback): Get rid of the timeout when the object
	is destroyed.
	(show_index_progress_bar): Connect handler to get rid of the
	timeout when the object is destroyed.
	(show_indexing_info_dialog): Move code that puts up dialog into a
	new function. Also use nautilus_gtk_window_present to put up a
	window. Change the NautilusLabel to use line wrapping.
	(show_search_service_not_available_dialog): Put this dialog in its
	own function so you can use it multiple times.
	(nautilus_indexing_info_request_reindex): Put HAVE_MEDUSA around
	the content of this function.
	(nautilus_indexing_info_get_last_index_time): Put HAVE_MEDUSA
	around the function, with a small simple implementation for the
	other case.
	(nautilus_indexing_info_show_dialog): Put HAVE_MEDUSA around the
	function, with a small invocation of the "not available" dialog.

	* src/nautilus-main.c: (main): Remove redundant AUTOHELP.

	* src/nautilus-search-bar-criterion.c: (make_emblem_value_menu):
	Fix emblem_name storage lifetime problem.

	* src/file-manager/fm-icon-view.c: Whitespace tweak.
