	Work done to improve the mime tpye capplet.
	Enable the capplet to be launched with a mime type.
	If a mime type is an argument, have the capplet scroll
	to that item in the list before the user begins interaction.

	* mime-type-capplet/nautilus-mime-type-capplet.c: (main),
	(list_move_vertical), (list_moveto), (list_reveal_row),
	(init_mime_capplet), (populate_mime_list):
