Script Summary: Show repo issues on the repositories page (https://github.com/:user)
Show a repo issues count on the repositories page (https://github.com/:user). The count is added next to the number of forks with a little bug icon. This count also includes pull requests, which technically aren't really bugs, but get included in the count anyway.
To prevent spamming the API server, only the first fifteen repositories, the ones showing a participation graph, will show the issue count.
