dan c3cff33f99 - Sort font styles in this order: Normal, Normal Italic, Bold, Bold Italic
in the font selection panel
- Added code to get the closest match font between the font in the WindowMaker
  domain and the one in the font list of the font panel in WPrefs.app.
  This fixes issues with not selecting the correct font because the weight
  or slant names are slightly different.
