Claimed Player Stats Panel (total points, stats viewer rank?) on /demonlist page

[kittylines]

also suggested in hq initially, after oauth is implemented, show some form of a marker next to or on levels indicating the user has completed or made progress on said level. (Example of idea shown below from demonlist+ extension by codekat)

On top of this, potentially show player rank and amount of points on the stats viewer on /demonlist too, perhaps on the sidebar. no mockup for this one unfortunately.

We've implemented the demonlist+-style progress and point indicators in #260. A panel with stats viewer stats on the sidebar would be nice too though (I missed that part of the suggestion when first reading this issue), so will look into that!
