Building persistence

Buildings will now persist their faction in the database. At least
that's what I want you to believe this change is.

What it actually is: A rework of InterstellarCluster and groundwork
for further reworks.

InterstellarClusterService: This is the old InterstellarCluster, but
as a service (it has always been one in secret). It was converted to
a typed actor and it now handles all spawn point requests.

ZoneActor: Basically ZoneControl, but as a typed actor. It's more of a
stub right now, the eventual goal is to have it own the `Zone` object
rather than the other way around.

BuildingActor: BuildingControl, but as a typed actor.

Also includes some minor improvements to ChatActor and sets
SupervisorStrategy.restart for all typed actors (which is the default
for classic actors, but not for typed actors - we may want to get more
sophisticated here in the future).
