Martin Atkins 7f99a8802e addrs: MoveEndpointInModule.SelectsResource
This is similar to the existing SelectsModule method, returning true if
the reciever selects either a particular resource as a whole or any of the
instances of that resource.

We don't need this test in the normal case, but we will need it in a
subsequent commit when we'll be possibly generating _implied_ move
statements between instances of resources, but only if there aren't
explicit move statements mentioning those resources already.
