Remove ThreadedWorldUpgrader patch

The patch does not implement Vanilla forceUpgrade behavior.
Specifically, poi/entity conversion and regionfile recreation.

The Vanilla force upgrader is also no longer broken by CB, so the
bug fixes from this patch are not relevant anymore.

-Subject: [PATCH] Fix and optimise world force upgrading
-
-The WorldUpgrader class was incorrectly modified by
-CB. It will store an IChunkLoader instance for all
-dimension types in the world, but obviously with how
-CB shifts around worlds only one dimension type exists
-per world. But this would be OK if CB did this
-change correctly. All IChunkLoader instances
-will point to the same regionfiles. And all
-IChunkLoader instances are going to be read from.
-
-This problem hasn't really been reported because
-it relies on the persistent legacy data to be converted
-as well to cause corruption. Why? Because the legacy
-data is also shared, it will result in different
-outputs from conversion (as once conversion for legacy
-persistent data takes place, it is REMOVED - so the next
-convert will _not_ have the data). Which means different
-sizes on disk. Which means different regionfile sector
-allocations. Which means there are 3 different possible
-regionfile sector allocations in memory, and none of them
-are going to be correct.
-
-I've fixed this by writing a world upgrader suited to
-CB's changes to world folder format. It was brain dead
-easy to add threading, so I did.
