Added Avatars next to messages

So far so good, avatars are now in place, doesn't look amazing but
there's a certain naive grace to the whole thing. At the very least one
could say that the layout is...honest.

Possibly almost ready to deploy this version to live, will have to run
more testing over the next 24 hours and then will give it a go in the
wild.

After that it's on to profiles again, first the design and then the
logic...

No rest for the wicked ;)
