  Last played sound name and current music name are display above their respective parameter.
• Add mutation parameter : Entities can now randomly change attributes like speed, range, size, if it's smart or not, and even change type.

  Chance to mutate by default : 10%
  Mutations chances : (Speed = 30%, Range = 30%, Size = 30%, Smart = 9%, Type = 1%)
