Use github as an issue tracker

[rafed]

A lot of open-source projects rely on Github issues for their issue tracker. Since researchers work a lot with open source repositories, I think it's extremely valuable to have a support for retrieving issues from Github issues and using it with SZZUnleashed.

Could this feature be added?

See the fork at https://github.com/fuhrmanator/SZZUnleashed/tree/master/fetch_github_bugs (it's not perfect, but it's a start). It's not been tested a lot with various repos (care must be taken in matching what is a bug, it's noisier on GitHub than on Jira).
