Platforms does not effect the ball

[bakscratch]

I'd like to have moving platforms that move the ball with it, at the moment the ball doesn't move with the platform stays stationary.

Also allow platforms to better push the ball, I have hammers that swing around and ideally should push the ball off the map but they just nudge them a bit at the moment.

The ball will stick to ground entities now, having other entities push the ball needs a bit more thinking though.

@handsomematt How can one build and run this?
