Rename ActorClone to Clone/2

Browse Source 
Step two: rename the object and its methods.

While we're at it, adhere more strictly to the coding style
practises; rename :clone-source to :source; add a setter method
for the :source property; take a reference on the source actor
to avoid it disappearing while we're still accessing it.
