[Rock-dev] Joystick and twice a std vector in RawCommand

[Matthias Goldhoorn]

The reason is that each axis could control several sub-axes.

The idea behin is that one one-dimensional arrays does not scale very 
whell with different kind of input-devices.
In the past it was one 1D array. We decided to change this.

If you have multiple input deviced, the mapping should be done by a 
conversion component. There could be no generic rule how to apply 
RawCommands to something else.

You joystick-driver should output the values from the Joysticks as they 
are. The mapping for your rover's should be done in a specialized component.

So no i'm against a change here.

Best,
Matthias
