Invite context

[lampholder]

I'm sure we've discussed this before but I can't for the life of me find the issue.

Anyway, it would be nice to share some additional context when you invite a user to a chat room - this could (and perhaps should) be as simple as a message from the inviter. To try to avoid misuse as a spam/harassment vector, I think the invite UX should hide the invite context by default.

I mocked this up a short while ago, but the idea came up in conversation today so filing as a suggestion here:

fwiw invites can now contain a reason field, we just ignore it.

@turt2live Is that documented somewhere? I would like to try to implement this.

nvm, found it in the unstable spec

#16300 is somewhat related. Maybe merging these into one wouldn't be a bad idea
