Entity handling improvements
Updates
Updated SyntaxApi to version 2.1.4
Improvements
Improved Entity.kill(); previously it wouldn't vanish the entities from the client, now it sends a packet which removes it on death
Improved Skin handling; Skins of players can now be downloaded via the MojangProfileServer class instead of the Mojang class which is for requesting skins for players
Improved SyntaxContainer for 1.14 - 1.16.5; Previously the container tried to call methods on the PersistentDataContainer with arguments which the PersistentDataContainer didn't support and therefore those methods will now throw a UnsupportedOperationException
Fixed
Fixed that all players on a server would be kicked if NmsPlayer.update() was called while no custom skin was set.
