Theme tab listed as first of the Preferences tabs makes tool inaccessible

Users cannot access the Preferences tool if the Sakai property {{preference.pages}} is configured to list the Theme tab first in the Preferences tool:

{}preference.pages={}{}prefs_theme_title, {}prefs_editor_title, prefs_hidden_title, prefs_noti_title, prefs_timezone_title, prefs_lang_title

For such instances of Sakai, users will see a '404' page when attempting to access the Preferences tool.
