A couple changes to my Grunt.js file

Hey! I'm looking for a skilled programmer who can help me with a few changes to my [login to view URL] file (see attached file). - I want you minimize, concat and create source maps for my js and css files (I know that a source map already is created for my css file. - I want you to rename files (css and js) for browser caching purposes. And it's important that these changes automatically will be applied to my [login to view URL] file (see attached file) - Make sure that everything that should be done is done with the build process. e.g. make it a awesome grunt file when it's done for grunt serve and grunt build. It's also important that you write comments in the file like the once that already exist.
