Added creeper object to enable desktop and VR users to work under the car.
- Interact with the creeper head rest to use the creeper.
- Move using normal inputs (slower than normal, and VR teleport is disabled).
- Desktop: Rotate creeper with creeper turn inputs (default left/right angle brackets).
- Desktop: Exit creeper by standing up (default space bar).
- VR: Exit the creeper by adjusting crouch/stand height (see below).
VR:
- Allow VR players to crouch/stand, enabling better play for seated users.
- Hold forward on the right thumbstick/pad to enter crouch/stand adjust mode.
- While in crouch/stand adjust mode, use the left thumbstick/pad forward/back to adjust standing height.
- While in crouch/stand adjust mode, press the use button to reset standing height.
- Automatically reset location and crouch/stand height under some conditions (e.g. putting head through wall/floor)
Desktop:
- Restrict minimum crouch height.
Add missing 29mm socket to impact socket kit.
Minor tweaks and bugfixes.
