Allow blocking invites from people you don't share a room with

Matrix currently has a significant moderation loophole, thanks to invites. Right now, anyone can invite anyone to a room - and clients like NeoChat will gladly display these rooms to them and even give you a notification.

However, this creates a pretty easy attack since room names and avatars are arbitrary and this is a known vector of harassment in the Matrix community. There's currently no tools to block this server-side, so let's try to improve the situation where we can.

This adds a new setting to the Security page, wherein it allows you to block invites from people you don't share a room with. This prevents the notification from appearing and NeoChat will attempt to leave the room immediately.

Since this depends on MSC 2666 - a currently unstable feature - the server may not support it and NeoChat will disable the setting in this case.
