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.

[compat] Fixed GalactiGreg ore generation

Fixed /custmsg possible client crash

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

[optim] Optimized vanilla leaves decay

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

Fixed strip color sequences from log file

Fixed /killentity

Fixed /vanish lang

[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

Fixed 10bec8e13a PendingBlockUpdates and EntityFallingBlock processing after chunk populating

Revert "[optim] Entity.random replaced to ThreadLocalRandom (it's really faster)" ...

This reverts commit 3aa3ad9.
(Issues with some mods that uses random seed)

I18n for duration format & restart messages

Correct error-reporting on unknown WorldType and not equal generation settings in worlds.yml and level.dat

More appropriate behavior of not splitted world mode (splitWorldDirs: false)

[refactoring] typos in class names

[optim] Entity.random replaced to ThreadLocalRandom (it's really faster)

Added PendingBlockUpdates and EntityFallingBlock processing and EntityItem removal after chunk populating ...

Newly populated chunk contains lots of PendingBlockUpdate and EntityFallingBlock, that takes lot of memory. PendingBlockUpdate processing causes more EntityFallingBlock spawning. In its turn, processing of EntityFallingBlock causes PendingBlockUpdate scheduling again. It solves by multiple iterations of processing both PendingBlockUpdate and EntityFallingBlock. Finally, we removing any EntityItem, that may be spawned at that time

Fixed /memstat "Off-Heap chunk used" more than 2gb

Fixed JLine tab completion

Issue #48 CPU utilization ...

Now we calling utilizeCPU method instead of Thread.sleep in in main server loop. In this method we can do something more useful than sleep. Currently implemented SyncServerExecutor queue processing and chunk generation

Fixed lots of issues with /genworld command

World generation limited to one chunk per tick

[optim] ChunkSendManager enhancements: ...

- min player moved distance is now directly proportional to viewDistance
- used back sort for toSend list (to remove values from end of list without copying)
- toSend list is now sorting only before sending (if necessary)
- removed unnecessary setWorldDestroyed method

[refactoring] unused var & typos

Fixed chunk sorting with large view distance (> 15)

[refactoring] Var name typos

[compat] Fixed mod-supported interworld teleportation (MystCraft)

Max view distance is now 32 (15 by default)
