- Add Firmata 2.5 features:
- Serial feature. See examples.
- INPUT_PULLUP pin mode
- SET_DIGITAL_PIN_VALUE (set a single pin value rather than an entire port value)
- Switched from AdvancedFirmata to ConfigurableFirmata in order to add Serial feature and more easily support adding new features going forward.
- Updated breakout-server and moved to its own repo
- Lots of code formatting updates
