This doesn't work 100% reliably yet, but the world server should now try
to commit your player back to the database if it detects you disconnect.
I also fixed a mistake where the global server state never removed
clients when they errored out. There's now code to remove your actor
from the instance when disconnecting, but this doesn't work reliably yet
either.
This makes the Teleport action functional now, although it looks pretty
rough as it warps you instantly instead of waiting for the action to
actually finish.
This begins figuring out how we are going to be propagating actor
control state: e.g. targets, poses, and other misc effects. I ended up
sending client triggers to the global server state, who then creates the
needed actor control packet for the other players.
Now players can see what other players are targeting!
