Should bounce be used on the platform sides?

When false, a contact on the sides uses no bounce. When true, any existing bounce is used. This is useful to stop bouncing of a Collider2D when in contact with a vertical surface. The "sides" are defined as the edges perpendicular to the "top" surface(s) in local-space.
