Initial release of github2mr.

This is the initial release which is fully-functional and works
for myself, self-hosted github enterprise installations, and
privately hosted gitbucket installs.

It has not been tested against other systems (gogs, gitea, etc),
but reports of success/failure or patches would be most welcome.
