Rank indicators in history are low-res

[mislav]

I am on my MacBook with Retina display, and I see sharp images for class indicators, but rank indicators are low-resolution in comparison:

The CSS for these images suggests that there was some attempt of image swapping for high-resolution displays, but the separate CSS rule simply loads the same (low-res) image again.

My suggestion would be that, due to the lack of high-res images for this, simple numbers as text could be used instead? I don't think it's really visually important that the rank indicators be identical to how they look in the game.
