Set part.angle in Body.update.

Browse source 
This change fixes a discrepency between `Body.setAngle` and `Body.update`.

Calling `part.angle` should always return the world space angle of the part.

In `Body.setAngle`, `part.angle` is correctly updated for every part.
This maintains the invariant.

In `Body.update`, `part.angle` was previously not being updated.
This led to stale values returned for `part.angle`.
