Spottedleaf aabf676721 Prevent unloading worlds with pending player logins
Logging into an unloaded world isn't going to end well.
This may fix the cases of people seeing errors about regionfiles
being closed, as loading chunks in an unloaded world will cause this
as the regionfile cache is closed but not cleared.

Subject: [PATCH] Use getChunkIfLoadedImmediately in places
This prevents us from hitting chunk loads for chunks at or less-than
ticket level 33 (yes getChunkIfLoaded will actually perform a chunk
load in that case).
