Title: DrudeForce did not implement getBondedParticles()

This fixes a bug. The effect was that if you used a barostat on a system with Drude particles, the Drude particles didn't get translated by exactly the same amount as the parent atom, so the barostat needed to use tiny steps before they would be accepted.
