Award bronze, silver, gold and platinum badges

Instead of awarding a route badge only once:

Add a counter to each route badge stating how often you received it.

Award bronze badge at 1st reception of a badge.
Award silver badge at 5th reception of a badge.
Award gold badge at 10th reception of a badge.
Award platinum badge at 25th reception of badge.

Make those badges really look good. :slight_smile:
Initialize any already received badge to bronze badge.
