Full 2.0 Rewrite!

The entire plugin has been rewritten from scratch!

What does this change?

• Much more maintainable back end, way easier to contribute as well
  • Updates will be quicker, bug fixes will be easier and faster
  • The system is way more modular: there is very little hard-coding and bad practices (which is just better for everyone)
• More efficient; the tiniest little bit faster than the previous version, but you won't notice it

Additions:

• Added the ability to use and (&) and or (|) operators is specifications.
  • Example 1: /kill @a[tag=dog|cat&!rat] would mean "kill all players with the tag "dog" OR "cat", and they don't have the tag "rat"
  • Example 2: /feed @r[team=red|blue|green,tag=player&!staff,gamemode=!creative&!survival] would mean "feed all players on team "red" or "blue" or "green", who has the tag "player" and not the tag "player, who's gamemode is not survival or not creative.
  • Due to the logic of how it work, you always need to put all of your OR statements before your AND statements, so for example, /kill @a[tag=red&blue|green] would NOT work, due to the implementation of this system.
