Fix and strip down facebook

Remove unstable non-working facebook semi-automatic token renewal (a simple warning on morss.it should be enough). Also commited some forgotten stuff.
Remove some useless options

progress and a accidentaly-disclosed one, cause useless
Try to use more generic 302/303 redirections

Still far from being great, but at least I can use it on both morss.it and test.morss.it now
