Octohat

Changed
- pagination now uses `per_page` 100 (thanks boneskull)

BugFix
- consolidating duplicate wiki and github contributors corrected (thanks boneskull)

Added
- Ensure Python 3 by adding blockers in `setup.py` and `__main__.py`

Changed
- project is now a module, which allows for easier local debugging
- removed duplicate wiki contributors from main repo contributors

Bugfix
- confirm git is available within the environment before using (thanks rogeriopradoj)

Added
- Ability to parse and add custom contributors based on a specially formatted CONTRIBUTORS file

Changed
- Relabelled report; was "Code/Non-Code Contributors", now "GitHub/All Contributors" (thanks ossanna16)
- Note: "All" is a superset of the old Code + the old Non-Code (hence, "all").
- Wiki contributions are always checked, and nicely fails if there's no wiki associated on the repo
- All old flags removed from the help. Kept for backward compatibility, though (thanks mjec)

Added
- Wiki Contributions are now included in the report, based on a list of authors of the username/repo.git repo
- Note: This uses local git repo cloning, as there is no github wiki API

Deprecated
- HTML Output. Deprecated in favour of the web-based [HatRack](https://labhr.github.io/hatrack/)

Bugfix
- Corrected pagination logic for GitHub contribution endpoint.

Added
- Flag to disable local cache (thanks edunham)
