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] Optimize ServerLevels chunk level checking methods
These can be hot functions (i.e entity ticking and block ticking),
so inline where possible, and avoid the abstraction of the
Either class.
