Set stage boundaries to ()

The set stage boundaries to () block is a stack block and a physics block. It changes the boundaries of the stage to one of 3 options:
* boxed stage - An invisible wall around the stage
* open (with floor) - Removes the 2 walls and the ceiling
* open (no floor) - no invisible wall
== Documentation ==
Adjust the physics of all sprites. Choose a type of containment to keep sprites within the stage.
* Boxed stage: Keeps sprites from going off the bottom and sides.
* Open (with floor): Keeps sprites from going off the bottom.
* Open (no floor): Removes all boundaries; sprites can go wherever they want.https://extensions.turbowarp.org/box2d
