title: Angular $resource date string gets decoded
body: <p>I'm using angular to perform a rest call to limit by date like so:</p>
  
  <p><code>endpoint.com/myAction?date=04/29/15</code></p>
  
  <p>But it gets decoded to this:
  <code>endpoint.com/myAction?date=04%2F29%2F15</code></p>
  
  <p>I'm instantiating the angular $resource like so:</p>
  
  <pre><code>app.factory('SessionResource', function () {
      return $resource('endpoint.com', {date: '@date'}
  });
  SessionResource.get({date: '04/29/15'};
  </code></pre>
  
  <p>There a way to pass in my date query parameters as a string so that it doesn't get encoded/decoded?</p>
