Adds status page showing number of open pr's per repo.

A few things:

1. Do we need to start using Bower now or should we wait? I'm asking because this requires jquery and a plugin to run. Managing them with Bower will be ideal but not sure if it's worth it yet.
2. Maybe `status` is not the right name for this page?
3. I ran into the github api rate limit (60 requests per hour for unauthenticated requests). This might be an issue since there are around 13 repositories. If you refresh the page a few times per hour you will hit the limit.

Thoughts?
