[Script] Simple wall ride

This script was requested by Ghost rider users, they want the wall ride feature available for any vehicle, so i did. Very simple script, the idea is get the car direction while its on ground, then activate the effect pushing the car up and rotating it to make it touch the wheels on the wall, then apply some force in the direction saved (the one saved when car was on ground) and apply some force up to avoid the possible fall of the car, when user accelerates the car just drive on the wall hehe:
