Mapper / tournament winner / etc. on player pages #346

I think this would be a nice QoL. I think people like clout and fancy titles, and I think all the information to implement this already exists (https://ddnet.org/mappers/, https://ddnet.org/tournaments/)

I also think some more 'style' on the global points + rankpoints place would be nice (i.e. a gold rounded div around their rank if they are in the top 100)
