Issue description:
After putting a body in a kinematic mode, and returning to rigid mode, it seems like gravity force is not working anymore on that body.

Steps to reproduce:

1. Check sample project

or alternatively:

1. Put a body in kinematic mode
2. Wait 0.1s
3. Change mode of body to back to rigid

Cutest bug demo ever :)

I fixed it. Anyway the kinematic body is like a static body and can't wakeup a rigidbody, the result is an overlapping between kinematic and sleeper rigid body.

I'll add a code to the function Move that add a force in case of kin touches the rigidbody so you will be able to push rigidbody even if they are sleeping.

If you create an issue with this feature request is better, so I can't forgot it.

@AndreaCatania I will, but you need to know it was putted inside reproduction project by total accident... Wanted to record nice gif with zerro-g floating bodies that were pushed by kinematic one :)
