Initial Commit. Able to set configuration settings for the RN2483 dev…

…ice. Implemented with the rn2483_radio_set_cmd function which uses an enum to represent each cmd and sends a radio set <message> to set the desired values of the corresponding cmd. void *data is the generic pointer which will be set to different data types, so appropriate pointer casting was used. All inputs to the radio_set_cmd function are presumed to have already been checked, which is why there are no checks in the function itself. A dummy file_read call is a temporary fix to get rid of an annoying bug where the 'sys get ver' value would be the first values in the read buffer after startup. Logging is used mostly for debugging at this point through syslog.
