Powerplay added, and complete field revamp! (V2.0 recap)

A nice handful of things have been added in this update!

• The centerstage field has been revamped completely
  • Including even the scoring elements and backdrops :)
• Powerplay field added!
  • Including a scoring element
    • However, there is no spawner yet

• I removed the necessity for contact with the floor for movement, as it sometimes bugged out
• I also changed how some of the backend code works, however, these are changes that will probably not have a major impact
