* src/nautilus-sidebar.c:
	(nautilus_sidebar_set_uri), (nautilus_sidebar_update_info):
	Separated update_info into the parts that were about changing
	URI-based information and the parts that were about changing
	appearance only. The appearance-only parts are now called
	nautilus_sidebar_update_appearance. The	other parts were put
	back into nautilus_sidebar_set_uri.
	(nautilus_sidebar_theme_changed),
	(receive_dropped_color), (receive_dropped_keyword),
	(background_appearance_changed_callback): Made these callers
	use nautilus_sidebar_set_appearance. The bug was that
	theme_changed was passing NULL for the initial title text,
	but passing NULL wipes it out rather than doing nothing as
	was intended. The other callers were getting the current title
	text and then passing it back in; now they just leave it alone.
