Add font and color preferences. Unfortunately Qt doesn't have a color

picker widget so we're back to popping up dialogs. Move the contents of
monospace_font.{cpp,h} to wireshark_application.{cpp,h}.

Pango and Qt use completely different string representations for fonts.
Add a separate gui.qt.font_name preference so that they don't clobber
each other.
