Hello! As per proposed in issues to nodebb-plugin-trophies I've added a widget area on the profile page. It is needed for nodebb-plugin-trophies, but hopefully will be handy for others too!

Thanks! I think perhaps you could think of a better name than "middle". "profile" maybe? Open to better ideas :)

"profile" is the name of the page, the template file itself. "Middle" is the reference to the visual location on the page, which is actually right in the middle :-D I don't know, do we have to have a better name for it?..

How about three widget areas, arranged like a WordPress triptych?
