This commit completely rewrites DisguiseManager, DisguisePlayer, and
PlayerDisguiseManager.
Changes to disguising means that much of the core was also changed,
primarily having to do with mapping by UUID versus player names.
Several new API classes were added, such as EntitySelector, Managers,
UtilTasks, and a brand new scoreboard API which is much more optimized and
allows for much longer lines
The new anticheat is hooked as well, with implementation for guardians
which follow the players around. Release two code is also included, but is
currently disabled via a boolean.
