Add a few ways to open profile for inviting users

I recieved a few invites from unknown users, and I had no idea who they
were/came from. I could check their profile to see if we had any rooms
in common, but there was no way to actually check their profile!

This makes it possible to open their profile by clicking their avatar
(like elsewhere) but also adds a button to make it even more obvious.
