This is achieved by injecting the NetLoginHandler when it's added
to the DedicatedServerConnectionThread's list of current login handlers.
PacketEvents during this phase uses "fake" Player objects that only
support a subset of methods. Consumers can expect the following methods
to be functional:
* getPlayer()
* getAddress()
* getServer()
* chat(String)
* sendMessage(String)
* sendMessage(String[])
* kickPlayer(String)
A "fake" Player object can be converted to its real counterpart by
calling getPlayer().
