Robotrainer fixes

This page summarizes problems to be solved concerning the robotrainer framework.

Essential:

• Update rate through ros_comm to allow more than 67hz. (Bøgild is looking into it).
• Connection is lost every 10mins or so. This happens at random, sometimes after a short while, others after 30 mins.

Non-essential:

• QT GUI's don't close immediatly when pressing ctrl-c in terminal. Only in record_ros_ui GUI.
