Camera to center on key held and center again on end

[judgejames]

1. Camera looks back
2. Camera doesn’t clip through head
3. Camera rotation locks
4. Camera centers when looking back (ideally it centers again when looking back)

Current version - it’s only looking 180 the other way from the current direction the player is looking before they hit the IA_Glance button, so there needs to be something that centers the camera before or after that button press.
