A very minor update.
Changes:
- fixed position of AC_TIME_0_R so that a new lap is registered when going through the pitlane
- fixed one small section of floating grass by Quarry
- reduced brightness of some lights
- moved metal box inside the fencing by Eymatt
- added custom normal maps to the spectators to improve lighting when using CSP
-double-checked collision meshes of all walls, to prevent 'grabbing' contact
