Improved Mobs 1.14.0

Big config overhaul. Do note that old config will need to be updated!
- Comments should be clearer now too
- Various configs now are able to use math expression to allow more customization
  - While the config will tell you if expressions are supported an indicator also is that values are strings instead of numbers
  - Usable variables for expression contains
    - difficulty: The current difficulty
    - distance_spawn : The distance to spawn
    - distance_origin: The distance to [0,0,0]
    - distance_center: The distance to the position defined in the config
  - For usable functions see https://github.com/Flemmli97/TenshiLib/wiki/Math-Expressions
