Motor status

For the motors/moveables we send data through the socketio. @marcus-oscarsson uses 'IDLE', 'BUSY', 'ABORT' in the beamline related signals. Looking at the AbstracMotor the following is defined:

    (NOTINITIALIZED, UNUSABLE, READY, MOVESTARTED, MOVING, ONLIMIT) = (0,1,2,3,4,5)
    EXPORTER_TO_MOTOR_STATE = { "Invalid": NOTINITIALIZED,
                                "Fault": UNUSABLE,
                                "Ready": READY,
                                "Moving": MOVING,
                                "Created": NOTINITIALIZED,
                                "Initializing": NOTINITIALIZED,
                                "Unknown": UNUSABLE,
                                "LowLim": ONLIMIT,
                                "HighLim": ONLIMIT }

Should we agree on the keywords we send for all the moveables? I would vote for the ones appearing in AbstractMotor, but I am not sure the reason for the difference, if any.
