Remove the 'Enable Twitter import' checkbox from Twitter admin panel by default; can be re-added with setting:

addPlugin('TwitterBridge', array('adminImportControl' => true, ....));

Added a note on the label that it requires manual daemon setup. (Note that by default the admin panel won't be shown, so it's no biggie to be hiding this for now.)
