title: Alter ResourceManager to split values by semicolon, not comma
body: <p>As the title says, is there a way to alter the ResourceManager's <code>getStringArray()</code> in a way that it splits the resources by semicolon, not comma?</p>
  
  <p>The actual method can be found in the <code>ResourceManagerImpl</code> class, which can be found in in the package <code>mx.resources</code>.
  Overriding that method would be fine, but ideally I'd like to write my own <code>getStringArray</code> with a variable separator, however, there seems to be no way of extending either the <code>ResourceManager</code> or <code>ResourceManagerImpl</code> class to somehow add that method.</p>
  
  <p>Anyone got a clue what to do here?</p>
