	Fixed bug #305.  CLicking in center of zoom control
	does not change zoom level.

	Clicking in the center of the zoom control emits a ZOOM_DEFAULT
	signal.  It is up to each view that connects to this signal
	to determine what is the default zoom setting.  Right now, all
	views are using NAUTILUS_ZOOM_LEVEL_STANDARD.  This could be
	changed to a zoom level better suited for the view.

	* libnautilus/nautilus-view-component.idl:
	Added zoom_default interface.

	* libnautilus/nautilus-zoomable.c:
	* libnautilus/nautilus-zoomable.h:

	Set up new ZOOM_DEFAULT signal.

	(fm_directory_view_restore_default_zoom_level):

	* src/file-manager/fm-icon-view.c:
	(fm_icon_view_initialize_class):
	Override zoom_default method.
