Removed the mavlink.h requirement from the Parameters library, and therefore the DataStore library as well.
Updated all usages to refer to the new PARAMETERS_DATATYPE enum.
Renamed Parameters functions. DataStoreInit() now returns whether the EEPROM had good data or not in it.
DataStore library not supports UINT16s. The rudder node now uses the Parameters and DataStore libraries and so the custom Nvram library was removed.
Also deleted the common.m file as it's now stored in Libs/MATLAB.
