Initial version integrate to Player in the branch feature-vib-belt-v2.
Currently it only prints that was supposed to be sent to the serial port.
Now, it must be tested with the actual vib belt.

2 features were created. 1st, the ranger2vib client converts the ranger data to the vib_belt driver, activating the belt when the robot is near to obstacles.

2nd, the GoDonnie parser has two new commands. cinto liga/desligado e vibrar f/t/fd/fe/te/td.
the 2nd cmd only works when the belt is on and it creates a pulse of 1s of vibration, then it stops.

See vib_belt driver and ranger2vib client to finish the code.
