Fails to build on Node.js versions above 0.10

[bergie]

Node 0.10 is unmaintained, so adding support to newer would be good. Some details in noflo/noflo-gpio#1

Hi, thanks for the report. I started updating the C++ to support the new V8 API, thus dropping support for 0.10 and 0.12 which are now deprecated. I got a version compiling and I did some test on a raspberry pi and a LED.

Tasks remaining before publishing:

• Test all features on RPi + BPi (GPIO/PWM/CapacitiveTouch)
• Test compilation on different Node.JS versions (I only tested LTS/6.9.3 so far)

If you want to check the progress or run some test yourself, you can pull from the v1 branch

Thanks for this, working great on Node.js 8.x
