Also move some functions out of the generic Application interface into
the specialized SocialApp interface. They will be moved back into the
Application interface if further development needs it when implementing
inbox forwarding, for example.
Also refactored the likes/liked add-to-collections logic so that they
are also applicable for following and followers collections. This code
is still as ugly as sin.
This was uncovered during writing tests where both the Social and
Federative APIs are enabled. The actorObject interface was overused
partially due to my earlier confusion; the introduction of the internal
actor interface resolved this.
Finally, the HttpClient interface was introduced to be able to mock out
calls in testing. It may also prove useful for future applications using
this library.
