Add better control for users of comments displayed on their videos:
* Do not forward comments from muted remote accounts/servers (muted by the current server or by the video owner)
* Do not list threads and hide replies (with their children) of accounts/servers muted by the video owner
* Hide from RSS comments of muted accounts/servers by video owners
Use case:
* Try to limit spam propagation in the federation
* Add ability for users to automatically hide comments on their videos from undesirable accounts/servers (the comment section belongs to videomakers, so they choose what's posted there)
* add quarantine videos feature
* increase Notification settings test timeout
to 20000ms. was completing 7000 locally but timing out
after 10000 on travis
* fix quarantine video test issues
-propagate misspelling
-remove skip from server/tests/client.ts
* WIP use blacklist for moderator video approval
instead of video.quarantine boolean
* finish auto-blacklist feature
