Add 'Reject and block user' button to invites

[frebib]

Your use case

What would you like to do?

Add a way to ignore an invite and block a user in one click

Why would you like to do it?

Because dealing with spam/abuse in Matrix is hard and this makes it just a little bit easier. Element Web has it and it's very useful

How would you like to achieve it?

With my finger

Maybe a 3rd button: (Accept) (Reject) (Block) Could do with some design input

Have you considered any alternatives?

Ignoring the invite, then finding the user somewhere and blocking them separately. It's considerably harder and slower doing that though
