* Move kick to PlayerConnection
* Redo Mojang LoginListener
- Move away from HTTPClient and use MojangUtils
- Add feature to prevent proxy connections
* Kick before handling exception.
* Update to throw IOException back to the login listener.
* Use PlayerConnection#kick in HandshakeListener
Also remove unused import left over in Player
* Removed clearItemUse() from refreshHeldSlot() because offhand
* Use 0 itemUseTime if the player is already using their mainHand and tries to use their offHand as you can only use one hand at a time
* Call clearItemUse() only when not using offhand, also refreshActiveHand
* Removed duplicate check
* fix: painting variants are now ordered and sent to the client correctly
* fix: use equals() to compare Strings

Mojang is somewhat inconsistent here. It is written over the wire as a var int, but the NBT type is a byte. DFU will coerce an int to a byte when reading so it is compatible to treat it as an int everywhere on our side.
* Duplicate property check
* increased bits per index
* fixed MAX_STATES error
* Block properties are now long, and new test for block state ID conversion
* Block properties are now long, and new test for block state ID conversion
* Block properties are now long, and new test for block state ID conversion
* excessive bits, and assertion fix
