icubmod: added debugInterfaceWrapper and changed icubmod/CMakeLists.txt accordingly

debugInterfaceWrapper is a wrapper similat to the controlBoardWrapper but for the
iDebugInterface only. Can be instantiated through the yarp factory and needs the
very same parameter of the ControlBoardWrapper and it can attach to the very same
motionControl device (no need to instantiate a new one).

First implementation
icubmod debugInterface Client: some fixes

- corrected cmakefile to have icubmoddev --list say it is a wrapper
- removed streaming port since it was never used inside the code
- restored get axes to enable runtime configuration.
     It does not uses position interface to avoid opening a polydriver, which
     won't work anyway
- fixed calls for all joints which were not working
icubmod debugInterfaceWrapper: removed redundant check and completed implementation
	of methods
icubmod debugInterfaceWrapper: added parsing message for all joint commands
