Added Pause Menu + Some Fixes

-Added pause menu, it doesn't actual pause the gameplay for competitive reasons (you could slow time with an AHK script)
-Added mouse smoothing setting
-Added sections in the input settings
-Added settings in the in game pause menu
-Fixed a physics bug that only happens on one specific road section by increasing the bounding box of sections slightly, it shouldn't affect anything else but let me know if you encounter some collision bugs (ex: your ghost doesn't reach the finish line anymore)
