In the new special page Special:AvailableBadges, all badges have the same icon (blue badge).
When the badges are used instead, each one has its own specific icon. For example, in Q12519:
- the Q17437798 badge (good article) has a gray icon
- the Q20748093 badge (validated) has a green icon
- the Q17437796 badge (featured article) has a gold icon
These icons should be used also in the Special:AvailableBadges .
