Subject: [PATCH] actors: Switch out address objects for more-easily-serialized
 cons cells

This is maybe temporary.  If we ever have canonical sexps as the
general serialization format, or something like that, we might revert
to a nicer structure.

* 8sync/systems/actors.scm (<address>): Commented out.
