I have unsuccessfully tried to spawn another actor, the game recieves it (and
adds it to the object table) but they are marked invisible. Besises, this also
contains various field improvements and initial support for social lists.
The current situation of throw-every-piece-of-logic-into-one-file for each
server isn't working out. So now there is a new ZoneConnection/LobbyConnection
struct that will be delegating tasks to their own Handlers (for example, there
could be a ChatHandler.)
I'm not sure how well this architecture will scale, but it's better than what
we have right now.
It's a hack and only really works going from New -> Old Gridania, but this does
work! It also means Kawari now actually requires a valid game installation,
since it has to read layer group information.
