Font Support in BottomFeeder

It turns out that you can not only change font definitions in VisualWorks, but you can save those definitions out to disk and reload them. I've added some basic support for that to the development upgrade path in BottomFeeder. After you grab the update, restart - there will be a new menu option under 'System' that allows you to define and save fonts. I'll be modifying that to allow newly defined font definitions to show up in the (short) list of defined fonts on the settings page, but I haven't gotten to that yet. Stay tuned. A few caveats - the underlying support in VisualWorks for this is not complete - on some platforms you won't see a full list of all available fonts.
