title: findAll with conditions in symfony2
body: <p>is there a way to use the <code>findAll()</code> function with conditions?</p>
  
  <p>I want to do something like</p>
  
  <pre><code>-&gt;findAll('active'=1);
  </code></pre>
  
  <p>I know that i can write custom repository classes but just for a simple "where-condition" I thought there is an easier way.</p>
