Fix Robotiq grippers flying around in pieces

[alexvannobel]

A misconfiguration in the mimic joint plugin would cause some chaos in the simulation for Robotiq grippers. Adding the flag did the trick.
I also added a couple fixes for :

• A deprecation in MoveIt (Kinematic attempts)
• Some colour for the Robotiq 140

This was the gripper before the fix:

This is the gripper after the fix:

Addresses #89
