Comment visibility #364

Add some support for comment visibility, fix #217

This add a new column to comment, denoting if they are public or not, and a new table linking private comments to those allowed to read them. There is currently no way to write a private comment from Plume.
Git is having a hard time what happened in Comment::from_activity, but most of it is just re-indentation because a new block was needed to please the borrow checker. I've marked with comments where things actually changed.
At this point only mentioned users can see private comments, even when posted as "follower only" or equivalent.

What should we do when someone isn't allowed to see a comment? Hide the whole thread, or just the comment? If hiding just the comment, should we mark there is a comment one can't see, but answers they can, or put other comments like if they answered to the same comment the hidden one do?

just 👀

What you have done seems to work great. 👌 The only little bug that I noticed is that when you are not connected but that there are private comments, the comment area is displayed normally but is empty.

I think that when a comment can not be displayed in a thread, there should a message saying it I think (it would fix the little issue I described too).

I've added a message, I'm not too fan of how it looks. I wonder if we shouldn't build the comment "tree" and trim it according to users rights before rendering, entirely hiding private threads

If that's not too complex, yes, it could be a good idea.

Great job, thank you!
