implement the CORBA side of dragging.

2001-05-12  Chris Toshok  <toshok@ximian.com>

	* e-storage-set-view.c (tree_drag_data_received): implement the
	CORBA side of dragging.
	(convert_gdk_drag_action_set_to_corba): rename
	convert_gdk_drag_action_to_corba to this.
	(convert_corba_drag_action_set_to_gdk): rename
	convert_corba_drag_action_to_gdk to this.
	(convert_gdk_drag_action_to_corba): new function that doesn't
	build a bitmask, useful for the Action types, instead of
	ActionSet.
	(convert_corba_drag_action_to_gdk): same.
