Added and changed some stuff

Epic finally fixed an issue that prevented me from updating (really my fault for updating UE to 5.5)

- Lumen and raytracing is gone, wasn't happy with it. Had to redo lighting and it's not perfect, but looks better than before imo.
- Added explosives
- Fixed eyebrows disappearing when zooming in on character.
- Added Climber Vision™ (Hold Q to highlight ledges you can grab)
- Other stuff I forgot
