RABG: Add Beaten Badges to RetroAchievements

Shows your beaten games alongside mastered games in the Game Awards section of RetroAchievements profile pages.

On a RetroAchievements user profile page, this extension: 1. Reads the "Completion Progress" list for every game marked as "beaten". 2. Sorts them by completion percentage (highest first). 3. Adds them to the "Game Awards" grid with a silver frame. 4. Adds a second counter with a silver crown icon for beaten games. At the very bottom of the page (i.e. the footer section of the website), there'll be a settings section that lets you adjust the way the beaten badges are sorted.
