Makign a get_latest_push function to find the first valid push to the user's actual
repos.
Rewrote the loop that populates the participants and deleted get_repo_from_url which
is useless now.
Added a bit more to the test in get_latest_push since find alone passed even when the
substring wasn't in the haystack string.
Adding commit message and commit url to the template context. Template is solid now.
