Term "censor" in Flow

Censor = suppression.

It used to be called "censor", but we've now changed all messages to "suppress". In code, however, everything is still called and referred to as "censor" (because it's not that trivial to get rid of). There's a patch to change all code occurrences of "censor" to "suppress" now, so "censor" may soon be gone entirely: https://gerrit.wikimedia.org/r/#/c/97751/

Until that is merged, you can rest assured that any occurence of "censor" actually means "suppress".
