* Region information is linked to simulators and track per sim
* Region information can be gleaned in callbacks now
* Parcel overlay handling is also done per sim
* Packets should be sent to the proper sim now
* Zerodecoding and appended ACK handling hopefully play nicely together
* Login timeout has been simplified, Simulator uses no timers
* Disconnect (from a sim) is currently broken at the NetworkManager level
* Periodic ACK sending and ACK appending is currently disabled
