title: Disable store load mask in Sencha 2
body: <p>The Sencha store is automatically adding a ajax loader mask when populating the store, but I want to hide it since I have made a more generic mask which is shown every time the app does a ajax request. </p>
  
  <p>How can I hide the store load mask? Tried to look in the documentation, but didnt find any appropriate field/method there:</p>
