Separate the preferences value for those flags and the name resolution code's value into separate variables; this means that the resolution code no longer depends on the preferences code, and may let us eventually have the current setting and the preference setting differ (so that a user can temporarily override the preference setting without causing subsequent saves of the preferences to save the temporary value). Add routines to create various types of widgets for preferences, and to fetch the values for "enumerated" preferences, and use them both in the code to handle hardwired preference pages and table-driven preference pages. svn path=/trunk/; revision=4536
