Minor update and graphics options
We made some minor updates to some of the scripting and also added graphics options back to the menu that were lost in the transition to Unity 2020. They aren't pretty, but they'll do and prevent the shadows from looking gross if your game gets set to toaster mode for some unknown reason. We are also working on making the brightness setting actually work. (updates currently only applied to WIN exe)
Long live Display Resolution Dialog (and bring back func_vehicle while we're at it).
