title: grunt build or bower adds a useless dependency for highstocks
body: <p>I'm using yeoman, grunt and bower and highstock library.
  When I build my app (grunt build) this generate these 3 lines</p>
  
  <pre><code>&lt;script src="bower_components/highstock/js/highcharts.src.js"&gt;&lt;/script&gt;
  &lt;script src="bower_components/highstock/js/highstock.src.js"&gt;&lt;/script&gt;
  &lt;script src="bower_components/highstock/js/highcharts-more.src.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>BUT, as highstock includes high charts this line should not be there and this makes errors</p>
  
  <pre><code>&lt;script src="bower_components/highstock/js/highcharts.src.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>the error is <a href="http://www.highcharts.com/errors/16" rel="nofollow">http://www.highcharts.com/errors/16</a></p>
  
  <p>How to remove this line in the build ?</p>
  
  <p>Thanks for your help.</p>
