* src/nautilus-sidebar-title.c: (update_icon):
	made the sidebar get the right icon for the hardware
	view by special-casing it like we do for services and man.
	As part of this, I made the sidebar work properly with
	.svg icons by calling the icon factory to load the icon.

	* libnautilus-extensions/nautilus-icon-factory.c:
	(nautilus_icon_factory_get_pixbuf_from_name):
	added a convenience routine to fetch icons by name.
	* libnautilus-extensions/nautilus-icon-factory.h:
	definition for the convenience routine.
