Mac: Switch to using NSFontManager fontWithFamily instead of NSFont fontWithName fontWithName: required the PostScript font name which could be the same as the family name, but often had no spaces, or extra text associated. Since we need to use the shared font manager, pull it out of the font chooser. Also "New Times Roman" worked on most platforms but required "Times New Roman" on Mac, so hopefully this will work on other platforms too.
