N-API CMake.js build

[msatyan]

CMake.js is a Node.js native addon build tool which works exactly like node-gyp, but instead of gyp, it is based on CMake build system. With this we don't need Python anymore (node-gyp on windows still dependent on Python 2.x). There is no change have done to the default node-gyp build, the CMake build is an addon. Once we got enough confidence with the CMake build then we could remove the node-gyp build facility in future. https://github.com/cmake-js/cmake-js

Not had chance to try this but this sounds awesome :) - currently experimenting with edits to the the binding.gyp and this might make that easier.
