browserify:app task fails

[fhightower]

Even after having fixed #1 , I am still getting the following error when trying to build the app (grunt build:dist):

Running "browserify:libs" (browserify) task
>> Bundle TCS_-_SampleApp_v1.0/ui/scripts/libs.js created.

Running "browserify:app" (browserify) task
>> /.../TCS_-_SampleApp/node_modules/ng2-device-detector/index.js:1
>> import { Injectable, NgModule } from '@angular/core';
>> ^
>> ParseError: 'import' and 'export' may appear only with 'sourceType: module'
Warning: Error running grunt-browserify. Use --force to continue.

I have setup my dev environment using the script here: https://gist.github.com/fhightower/9ae9438ff7bad53ae6bae6a32385842e
