split "highlighted" into self_highlight and child_highligh.

	* e-folder.c (_EFolderPrivate): split "highlighted" into
	self_highlight and child_highligh.
	(e_folder_get_highlighted): Return TRUE if either self_highlight
	is true or any child is highlighted.
	(e_folder_set_child_highlight): New function to tell the folder
	about a child highlight change.

	* e-storage.c (folder_changed_cb): Update child highlights
	correctly on folders so that folders will be highlighted whenever
	their children are.
