Changed lighting and skybox a lilttle bit, its brighter, I might change it back not sure rn

added utilities panel with some useful stuff and experimental stuff:
- remove allies
- remove turrets
- spawn manhacks (experimental)
- spawn aerial abominations (experimental)

added ladders and roof area

fixed spelling of assault for "assault over" message

added new explosive box that's kind kinda useless but funny to me

potentially fixed ally turrets attacking ally rebels for some people

"just foolin" is easier and "assault vehicle event" has more tanks

added more airspace for future gunship and other flying shit

added cubemaps and navmesh
