Command alias maker

Added per world/server support and added /galias command for global aliases. This is the fixed version of #4

My testing seems to work on 1.20.1 and 1.21.8 and 1.21.4 and 1.21.1 and 1.21.6 and 1.20.6 and some stuff in between but I havent tested all versions. Pretty sure it supports most of them though. Anyway I removed some feedback since its annoying and I have an additional file that has no feedback at all

Added support for pretty much all the versions and improved command registration to be instant.

Initial release tested on 1.21.1 and 1.21.2
