Subject: [PATCH] Configurable Chunk Inhabited Time
Vanilla stores how long a chunk has been active on a server, and dynamically scales some
aspects of vanilla gameplay to this factor.
For people who want all chunks to be treated equally, you can chose a fixed value.
This allows to fine-tune vanilla gameplay.

Subject: [PATCH] Optimize isValidLocation, getType and getBlockData for
inlining
Hot methods, so reduce # of instructions for the method.
Move is valid location test to the BlockPosition class so that it can access local variables.
Replace all calls to the new place to the unnecessary forward.
Optimize getType and getBlockData to manually inline and optimize the calls

Subject: [PATCH] Sanitise RegionFileCache and make configurable.
RegionFileCache prior to this patch would close every single open region
file upon reaching a size of 256.
This patch modifies that behaviour so it closes the the least recently
used RegionFile.
The implementation uses a LinkedHashMap as an LRU cache (modified from HashMap).
The maximum size of the RegionFileCache is also made configurable.
