Investigate changing head tilt velocity damping to allow more torque (ros ticket #4919)

[ahendrix]

Currently, the head_tilt_joint has a k_velocity of 1.5 in the URDF. This has the effect of limiting the max torque the joint can apply to half its possible value.

We need to look into changing this value to 3.0 to see if the head tilt performance can be increased. We'll have to validate any changes using our HW test systems.
