TinyMCE Quattro and its wysiwyg bbcodes 2.5.2

This update focuses again on the font family and font size buttons.

• New option to select icons buttons for font-family and font-size
  buttons
• The font-family & font size icon mode has been improved
• The selection of the font-family & font size buttons (icon mode or
  not) should now be visible when the button show (scrollto function)
• The menu of the font-family and font size buttons have now the same
  fix that was done for the color/bgcolor buttons when the fullscreen mode is enabled (needed with XenForo. Why ? No idea)
• Add a TinyMCE command to reset the fright buttons (needed to avoid any glitch) when the state is changed
