Closes #35, #32
Fixes #33, #36, #37, #39

Complete rewrite of this plugin, more versatile code and bug fixes.

Instead of having to define each entity individually, get entities directly from the EntityType enum, which includes every entity.
Infer every relevant entity information from the entities interface, instead of doing it manually, with the option to change values as needed.
Run entity updates on a timer instead of repeatedly creating new tasks.
Renamed variables to more clearly indicate their use.
Changed internal entity IDs.
Created modules for better readability of source.

Config needs to be deleted if an earlier version was used
