Roly Poly Buggy Mechanics

[heberross]

Roly Poly buggies should be added into the game with a unique movement functionality to set it apart from the other buggies. The buggy will be able to be ridden when its rolled up and when its crawling around like normal. Once its rolled up it uses momentum to move and deal damage. Build pieces can be used as ramps to gain speed for the buggy while its rolling, and if it rolls off of a ramp it can be launched high up and doesn't take fall damage in this state. The buggies momentum can also deal damage to bugs based on the speed it is moving.
