Added more detail to the map. most notibly:
- Hatch area and spawn got some extra or improved detailing
- Skybox added
- Minor tweaks relating to the visuals and clipping making it have more sense and not give the illusion of a 32hu high wall you cant jump over
- Concept version of advanced 2 with 2 waves added
- Advanced 1 modified to contain less money (a slight difficulty increase)
- Minor adjustments to clipping to allow certain props to be jumped directly (no longer requires crouch jump)
