* libnautilus-extensions/nautilus-search-uri.c:
	(nautilus_search_uri_to_simple_search_criteria):
	This needs to return a g_free'able string, so I changed the
	placeholder to return NULL instead of "". (g_strdup ("") would
	also have been OK.)

	Got rid of set_search_controls since set_location does exactly the
	same thing. Changed to use get_location in the
	NautilusNavigationBar base class instead of having lots of
	separate get_location. Fixed bug where get_location would return a
	non-g_strdup'd string, which callers would then g_free. Also
	changed to use simpler version of location_changed since the
	navigation bar can now get the location easily for itself so the
	subclasses need not do it. Callbacks now can call
	nautilus_navigation_bar_location_changed directly. Removed some
	empty destroy functions in classes where they are likely to be
	empty forever.

	* src/nautilus-window.c: (goto_uri_callback): Whitespace.
