Add sequence number to Actors

When actors with duplicate names are loaded, a way is needed to
determine which should take precedence. Added a sequence number to
Actor to facilitate this.  Unfortunately, couldn't use OrderedServiceImpl,
because it only creates the Actors once, which would break a number
of junit tests.
