Added Wallrunning

-Added Gravity() function for all future effects to gravity
-Wallrunning functions as follows:
    -If player isn't grounded & is moving forwards
    -If player is above minimum ground height
    -Check frontal directions with rays to see if we are hitting a wall
    -If yes - no gravity, if no - normal gravity
