** Fixes bug #557818

2008-11-17  Matthew Barnes  <mbarnes@redhat.com>

	** Fixes bug #557818

	* addressbook/gui/component/addressbook-view.c:
	* calendar/gui/calendar-component.c:
	* calendar/gui/memos-component.c:
	* calendar/gui/tasks-component.c:
	ESourceSelector now handles most of the drag-and-drop signals.
	We just have to listen for the new "data-dropped" signal and
	deal with it.  Gets rid of a lot of duplicate logic.
