pr2_description 1.4.0 URDF Belt Stretch Transmissions are unstable (ros ticket #4994)

[ahendrix]

I just tried running with the 1.4.0 version of the URDF on PRO, and the arms are definitely unstable. Changing the gains could possibly fix this, but more testing should probably be done to verify that the gains work across multiple robots.
