Added features:
- Mouse can be inverted (Settings -> Controls -> Mouse)
 - Keys to all actions can be re-mapped
 - Global volume controls (Settings -> Gameplay)
 
Fixes:
- Collisions should appear correctly now
 - Wirecutter should not crawl on the floor after load anymore
 - Wirecutter minigame should now work correctly
 
Experimental (I was not able to reproduce, but made a few changes):
- Keys should no longer disappear after opening the garage door
 - The scaffolding should work fine now
 
Note: The diagonal rod resting against the scaffolding is really NOT to be climbed. It is not a bug if you fall down from it.
