title: angular-translate: urlLoader with additional query parameters
body: <p>Is there an option to call <code>angular-translate</code> module (made by Pascal Precht) with additional GET parameters, not only with <code>queryParameter</code> one when using <code>urlLoader</code>? Current implementation is as follow:</p>
  
  <pre><code>  $translateProvider.useLoader('$translateUrlLoader', {
      url: 'endpoint/translations',
      queryParameter: 'language'
    });
  </code></pre>
  
  <p>and then in paritucar controller as:</p>
  
  <pre><code>$translate.use('en');
  </code></pre>
  
  <p>What i need to do is to call it with more parameters, like:</p>
  
  <pre><code>  $translateProvider.useLoader('$translateUrlLoader', {
      url: 'endpoint/translations',
      config: {
        queryParameter: 'language',
        secondParam: 'screen',
        thirdParam: 'client'
      }
    });
  </code></pre>
  
  <p>and then in particular controller to be invoked it as:</p>
  
  <pre><code>$translate.use('en','login','pepsi');
  </code></pre>
  
  <p>As result I need to call my API endpoint like:</p>
  
  <pre><code>endpoint/translations?language=en&amp;screen=login&amp;client=pepsi
  </code></pre>
  
  <p>Thank you!</p>
