Remove references to Facebook cross-posting
Facebook's new policy has broken cross-posting from external services, and it doesn't look as though there's going to be any way to fix that. D* has removed this feature entirely. I noticed that the dummy text in the services filter bar says 'Try: facebook AND twitter'.
I've found mention of Facebook in:
https://git.feneas.org/diasporg/Poduptime/blob/develop/showfull.php#L87 (change to
"Try: twitter AND wordpress"?)
There might be others; sorry, I haven't had chance to look through all files.
