Break bin/kss-node into reusable modules

[nkgm]

At the moment, there's a lot happening in bin/kss-node:

1. Handlebars helpers
2. Json functions
3. Page generator functions

Any build system that wishes to use kss-node has to replicate these functions verbatim. I think this functionality should be modularized.

Agreed. I would really like to make Handlebars be the default template system for the CLI. So that you could swap in your own templating system.

Can you speak more about this? I'm currently using gulp.js to build my KSS style guide and I just need to have my gulp tasks call the command line. No copying of code necessary.

gulp.task('styleguide', gulpShell.task([
    // kss-node [source folder of files to parse] [destination folder] --template [location of template files]
    'kss-node <%= source %> <%= destination %> --template <%= template %>'
  ], {
    templateData: {
      source:       theme + compass.sass,
      destination:  styleguide,
      template:     styleguide + 'template'
    }
  }
));
