For Salt projects have a badge for "$x of $goal funds raised" badge

In addition to bounty based badges (e.g. http://blog.bountysource.com/post/87257081709/bountysource-badges) add a badge showing how much has been raised toward a Salt project's monthly goal (e.g. "10% of $7,500 goal raised" or "$757 of $7,500 goal raised").
