Fix font setting

Several issues  mainly related  to the  rather complex  interaction of
style sheets and widget properties with respect to fonts.

Font setting  on the  astro window  should now  be consistent  and not
overridden by application style sheet driven font settings.

Decoded text font setting should now be consistent and not revert back
to Courier 10 on the next decode after a font change.
