[optim] Optimized some World methods by using getChunkIfExists instead of chunkExists + getChunkFromChunkCoords

[optim] Optimized RecipeCache - don't clear full cache on overflow - remove only oldest (by usage) entries

[optim] Optimized RegionFileCache - don't clear full cache on overflow - remove only oldest (by usage) entries ...

Also fixed possible deadlock

Update player chunk send queue on server coord changes (don't await client packet) ...

1. It is an optimization because we don't rebuilding chunk list on each player packet
2. It is an improvement because we don't awaiting client packet on player server coord change (like teleportation)
3. It is a fix because some client mods don't send coord update packet to server before first chu packet handling

Disable entity updating in worlds with disabled chunk loaders and no players ...

(previously 'enableChunkLoaders' option was ignored in this context)

Fixed Entity & TileEntity unloading in worlds with 0 active chunks (memory leak on world generation)

Prevent teleportation while riding entity

[compat] Fixed EntityLimiter & mob spawn for LycanitesMobs

Fixed kick from server if player with too long username connected

[optim] Optimized Chunk.scheduleBlockUpdate() ...

- use ShortObjMap with chunk coord keys instead of HashSet<PendingBlockUpdate>
  - deduplicate PendingBlockUpdate by coord
  - pool ShortObjMap and TreeSet objects

[optim] Little WorldServer.func_147456_g() optimizations (it is enough hot) ...

- removed unused variables
  - use ThreadLocalRandom instead of default world Random

[optim] Optimized World.getBlockIfExists()

[optim] Fixed Entity with old AI path recounting each tick if target is not reachable

Fixed player NBT data read/write out-of-sync ...

In ultramine core player data saves asynchronously, so it was possible to read OLD data after
NEW data requested to save, but has not really been written to the file.

[optim] Use buffered IO when writing non-compressed NBT to file

Fixed player renderDistance reset after death

[compat] Fixed GalactiGreg ore generation

Fixed /custmsg possible client crash

Fixed possible crashes caused by wrong eventProxy.startEntity(entity) placement

Fixed player lang reset after death

[optim] Optimized vanilla leaves decay

Fixed kick on invalid url in chat

[optim] Totally replaced LongHashMap & IntHashMap implementation to Koloboke collections

Fixed strip color sequences from log file

Fixed /killentity

Fixed /vanish lang

Fixed invisible players after teleportation

Throw IllegalArgumentException from DataWatcher if object id < 0 (fix for thaumicenergistics)

[optim] ImportChunkLoader disposing ...

Now we don't wait for finishing of writing all worlds. Waiting only for current world, then closing region files. Currently implemented for ImportChunkLoader only, should be implemented for default chunk loader in future

Better hash for in-chunk block coords
