title: NSTextView and NSAttributedString
body: <p>I'm trying to stick an attributed string into my NSTextView, but it's just showing as plain text, no attributes.  I created my string like so:  </p>
  
  <pre><code>    NSString *str = @"Parsing Directory Structure\n\n";
  
  NSMutableAttributedString *attrstr = [[NSMutableAttributedString alloc] initWithString:str];
  NSDictionary *attributes = @{
                               NSForegroundColorAttributeName : [NSColor blueColor],
                               NSFontAttributeName : [NSFont fontWithName:@"HelveticaNeue-Bold" size:20.f]
                               };
  [attrstr setAttributes:attributes range:NSRangeFromString(str)];
  
  [[self.textView textStorage] appendAttributedString:attrstr];
  </code></pre>
  
  <p>and on the NSTextView (inside the scrolling view) I've got the "Allows Rich Text" box checked still, and the Editable box unchecked.  I'm basically trying to use this like a console output window.</p>
