Fixed AHRS again. Interrupt based synchronisation works Well with atleast 4 sensors @ 50Hz
Added possibility to ask raw data from sensors
Now all sensors on board send their data
Now sensor-boards verify, that data has been sent from server and respond depending on message type
It should be possible now to change sensor-boards' calibration data (though this has not been implemented on server yet)
Accelerometer scaling and offsetting fixed
Magnetometer scaling and offsetting added
