Daniel Knox / RN2483

A mbed library for the RN2483. Heavily based on the Sodaq_RN2483 library for Arduino (https://github.com/SodaqMoja/Sodaq_RN2483). This is currently under-going initial testing, but seems to work! Tested on a NRF51 and FRDM K64F.

Commit message:
Have removed save functioanlity for now, due to a bug introduced. The potentially long delay between requesting to save and saving means the device is thrown out of sync with the returned 'ok' strings -- causing issues with the library.
