Test with running the ROS master on the device

To connect to the running master on the device, the ROS_IP environment variable has to be set to the computer's IP address, and the ROS_MASTER_URI has to be set to the device's IP address.
This allows the computer to read the loaded parameters, as well as change the published topics of the Tango Ros Node via dynamic reconfigure and display the topic information.

Nevertheless, when a launchfile is executed from the computer, the following error appears:

load_parameters: unable to set parameters (last param was [None]):  <Fault 0: 'No such handler: system.multicall'>

This happens even with simple launchfiles like map_to_odom from navigation_setup.

Aaah, I know why that is. The rosjava master is missing the 'multicall' implementation I think.
I think implementing it will be hard, so the best will be to narrow down which particular use cases cause this and see if we can restrict those use cases to a Linux master and still cover all the combinations we want to support.

Fortunately, this was solved in rosjava/rosjava_core#273.

Now launchfiles should work when running the ROS master on the device.
