title: TinyMCE 4 theme_advanced_fonts
body: <p><br/>
  I'm trying to add custom font family in TinyMCE Editor version 4.0b1 and keep failing.<br/>
  All default fonts show, custom fonts like 'Century Gothic' or 'Gill Sans MT' are not showing. Is theme_advanced_fonts not working in TinyMCE 4? I can't find any TinyMCE 4 documentation for this.</p>
