title: Android Lint Plugin - set custom warning / error that should be checked
body: <p>My question is if there is a way to add to lint plugin a custom check which it should warn me about before building a version. For example I want it to check all <code>Cursor, InputStream</code> objects in my code if they are closed, or to check my code for <code>//TODO:</code>, <code>//FIXME:</code>.</p>
  
  <p>Any ideas if there is any kind of way to do that, or even not with Lint Plugin?</p>
  
  <p>Thanks in advance!</p>
