Rework chat into Velocity-managed channels

Chat is now handled entirely by VelocityCore through channels with
separate readers and writers (Global, Local/Fight, Blue/Red fight team,
Team, ServerTeam, Alert and 1:1 direct messages). Each player has a
saved default channel; messages from other channels are tagged with
the channel name, and every default change is announced.

- /global, /local, /tc, /stc, /msg and /r switch the default channel
  when called without a message
- /chat <channel> switches, /chat <channel> join|leave toggles reading
  (saved); moderators can join arenas by name and write with
  /chat <channel> msg <text>
- '+' sends from global to local and from local/fight to the fight team
- Referees write yellow in the fight chat
- Subservers no longer receive chat; arenas get a record-only
  ChatRecordPacket so replays keep their chat
- Remove the chat listeners of SpigotCore, FightSystem, MissileWars,
  TowerRun and TNTLeague

Closes #460, #129
