Only adjust fonts that are actually changed

OK-ing the Fonts dialog now checks which fonts have been changed,
and only applies those to the widgets that use them. In addition it
sets a flag to indicate that the changed font no longer is a default.
 A bug that did not apply the gameListFont for preview is now also
fixed.
