UARTClass::init() muxes out the UART pins to Arduino header pins 0/1. Reset the mux on UARTClass::end() so that pins 0/1 can be used as GPIOs again.

@calvinatintel @eriknyquist +1 looks good to me |

@eriknyquist In case it helps, I've tested this and confirmed that it fixes the problem that I reported in #241. |
