SboxSuperuser/Engine/Bodies/NoclipMoveMode.cs
A MoveMode for the player controller that implements noclip, used by the superuser/admin tooling in this package. It scores higher than any other mode so it takes over, disables the collider and gravity, moves along eye angles at 3x run speed with jump/duck for vertical, and pushes the wish velocity straight onto the body.
