Add NodeJS/Electron support

[tresf]

Per request of @scream3r, the ability to abstract the native code and make the library re-usable for Electron/NodeJS support.

The new build setup I am currently creating will create jar files which will only contain a single .so file. Optionally I can add the header and create other archive types. I'd it this which was requested?

I've never written an Electron native plugin before, but the various tutorials seem to all mention a node-gyp utility and often a electron-rebuild utility which matches Node.js modules to a Electron-compatible version.

Electron wouldn't need the Jar file specifically, so this task would likely be more of an API-abstracting (or API-Electron-JNI-wrapping) task rather than a request for other archive types.
