align to/cc addressing pattern with friendica, hubzilla instead of mastodon
This MR aligns our addressing pattern for mentions with friendica and hubzilla instead of Mastodon.
There is no effect with Mastodon-like platforms with this change but it solves an important problem concerning Friendica and Hubzilla compatibility.
Now the mentions are calculated based on to
field and any tagged Mention
items. Accordingly, we also re-unify handling of Announce
activities which was separate before.
Closes: #341 (closed).
