v3.1.0

• Private and Public functions that allow you to hide functions from external libs
  func private secret() // private function
func public hello() // public function
func goodbye() // public function by default

• Broke window.c (great...), fixing it VERY soon.

• Added custom for loop enders (meaning that you do not have to do "--" or "++", you could do i+=3 for instance, to make i increase by 3 every time the loop body successfully runs)

• Added standard library, automatically includes core libraries and gives you the DynamicArray and File classes with their own dedicated functions

• Improved performance, especially on for loops.
