	** Fixes part of bug #557818

	* libedataserverui/e-source-selector.c:
	Allow the ESourceSelector widget to determine whether a drag and
	drop event is valid, and emit a new signal ("data-dropped") if it
	_is_ valid.  This eliminates a lot of duplicate code in Evolution.

	Note, while this is technically an ABI break, we explicitly
	decided NOT to bump the libedataserverui soname because the
	changes only affect Evolution.  And while we're at it, add
	extra padding to the end of ESourceSelectorClass to allow for
	future expansion.
