- Add methods to LimboService for handling messages to make it the only relevant Limbo class for outside classes
  - Move LimboPlayerTaskManager to limbo package and make it package-private
- Create MessageTask and TimeoutTask immediately when LimboPlayer is created
- #1112 MessageTask: improve efficiency by keeping reference to Player
