Improvements to async login

Browse Source 
Bump chunk priority to ensure chunks load fast
Handle case where client disconnects before they even fire PlayerJoinEvent
  - no longer call PlayerQuitEvent or print quit message.
  - don't save the player data file if never joined. Nothing has changed.
    CraftBukkit has a bug here that if you do save it, you will lose
    any horse that the player logged off on because the horse hasn't
    been resummoned yet.
