Spigot patch 0038: BungeeCord support [incomplete]

Allows BungeeCord to set the players real IP address very early in the login process, so that the BungeeCord proxy IP is never even seen by a plugin.

MCPC+ notes:

- This packet is handled directly in NetLoginHandler instead of
  through FMLNetworkHandler handlePacket250Packet or a registered
  listener since that's how Spigot handles it; could be changed later.
- BungeeCord does not yet support Forge, so this commit has no use yet.
