title: grunt-angular-templates cache all templates
body: <p>So I ran into an issue when trying to use toastr as a global error notification system in my angular application.
  This was logged as an issue with angular-toastr and the proposed solution was to push all templates into the templatecache. Apparently this is a good thing to do and after reading up on why, I have to agree.</p>
  
  <p>My problem is that I am really new to grunt (only just installed it today) and although I have now managed to successfully set up my gruntfile.js and run some tasks (minification, concatination, etc) using grunt-angular-templates is a mystery to me.</p>
  
  <p>I have set up my gruntfile like this:</p>
  
  <pre><code>ngtemplates: {
      options: {
          module: 'project',
      },
      dist: {
          src: [
              'wwwroot/lib/angular-toastr/**.html'
          ],
          dest: 'wwwroot/js/templates.js'
      }
  }
  </code></pre>
  
  <p>But my templates file that is generated is empty.
  I assume this is because scripts are creating in the JS files.
  Does anyone know how I can get access to the them so I can add them to the cache?</p>
