fb_uninstall() in fb.install blows away all settings for the fb_social module as well

fb_uninstall() in fb.install ...

function fb_uninstall() {
  db_query("DELETE FROM {variable} WHERE name LIKE 'fb_%'");
}

The fb_social module stores all settings as "fb_xxxx" as well. Would be better if DFF explicity deleted each item in variable table instead of relying on wildcard.
