The refactors in this commit go a bit beyond the scope of what the sound/effects branch was meant to accomplish, however most of these changes are necessary so chunk caching could be reintroduced for the standalone version. The chunk caching here allows for us to get the block ID before the block was broken, and in the future allow us to implement newer features. Chunk caching is optional (and disabled by default) as on non-Bukkit versions, it can eat up a lot of RAM with many players online.
This allows the description of the commands to display when listing the commands in bedrock by tab-completing. This is currently only available on Sponge and Bukkit versions as there is no support in BungeeCord and Velocity to get these values. This data is also not sent in any packet, so we cannot retrieve that from standalone either.
The normal identity UUID caused problems and caused the bedrock client to crash when using Floodgate. This was likely because on bedrock edition, it's a version 3 UUID opposed to java edition which uses version 4.
