Closes m-e-conroy/angular-dialog-service#37

When used with [Yeoman](http://yeoman.io/) [grunt-bower-install](https://www.npmjs.org/package/grunt-bower-install) adds both unminified and minified to index.html during build phase.

bower spec discourage added minified files to bower.json according to [bower.json specification](https://github.com/bower/bower.json-spec#main)

Please remove minified from main section in bower.json
