Oops, fixed bug introduced in previous commit. Have to check if DefaultPreferences is not nil, it may not be yet initialized.

Changed preference lookup. When a preference key is not found in the preferences object, then look to DefaultPreferences for the key. If not found, return passed default value. When initilizing "current" preferences, do not copt default preferences there, the following lookup would do. The advantages are: * when (installation-defined) default changes and user did not change the value a new default will automatically apply if changed (because it's not copied to user's current preferences and thus not saved) * allow for simple "reset to default" setting which can just remove the preference key from users 'current' preferences (then, the would be found in defaults)
