Easy way to seperate out Grunt stuff to avoid massive gruntfiles

Gruntfile.js

/*****************************************************

  Grunt'd

  This 'plop-in' plugin was created to expedite the
  process of adding the required files for front-end
  development.

  This includes template scss files and `main.js`

  Packages:
    -> grunt-uncss
    -> grunt-csscss
    -> grunt-contrib-uglify
    -> grunt-contrib-jshint
    -> grunt-contrib-qunit
    -> grunt-contrib-watch
    -> grunt-contrib-concat
