increase versioning - 0.4.1

partial fix for sinking through water

Optimised Craft movement in regards to WorldHandler (#23)

* Created new class `ChunkDataManager` and phased out `WorldHandler`

* Optimisation successful. 54k vtest type craft translating in 31ms.

* WorldHandler reduced to WorldUtils due to remaining methods; locationToBlockPos and moveEntity

* CraftRotateCommand and CraftTranslateCommand now have internal methods that directly utilise ChunkDataManager

Ensure release jar is up-to-date
