Add nRF51 USB Dongle dev board (#67)

* Added nRF51 Dongle

* added travils build for nrf51 dongle

* Added the chip configratiopn to the travis task for nrf51dongle

* travis task update

Adding a reference to which version of the board variant to build.

* Reduced the PIN defintion for the NRF51 Dongle

* Added S110 softdevice option to nRF51 Dongle

* Added nRF51 Dongle link to README
