title: QFileSystemModel hide certain files
body: <p>What I'm looking for is pretty much the opposite of QFileSystemModel::setNameFilters().
  I'd like to set filters that catch things I <em>don't</em> want to show, but let everything else through. I don't see any way to go through and hide certain files, because remove() actually removes the file from the system.</p>
  
  <p>How do I go about this?</p>
  
  <p>Edit for clarification: I have a specific list of filenames that I don't want to show. </p>
