Fix issue with detailed status view not supporting unreblogging/unfavouriting

Make replies default to privacy settings of the status being replied to

Fix #635 - Include the initially-reported status in report UI even if it's not
among the user's most recent statuses

in case of debugging incoming salmons. Add <thr:in-reply-to /> to favourite
salmons because it seems to be required by GS.

StreamEntry model. Simply render Salmon slaps as they are needed

I haven't had a chance to test this, because I don't currently have a fully functioning computer I can set up a dev-environment on, but this *should* make it so when a user toggles a post to be private, a disclaimer appears clarifying what "private" really means.

Add variable for text of privacy disclaimer

Allow PuSH to distribute private toots with that condition

if account lock info was up to date, otherwise re-do the FollowService
with now updated information

This should help federation

status is not in the system at time of distribution; fix #607 - reset privacy
settings to defaults when cancelling replies

Refresh timelines when streaming API reconnects in the UI
