GitHub download zip

A userscript adds download links so that downloaded filenames include the SHA

This userscript works on:
- Main repo page "Clone or Download" dropdown. The download link is modified.
- Repo commits page. Each commit can be downloaded as a zip file.
The dropdown may not show any content if the repo doesn't specifically define a release
- https://github.com/Mottie/GitHub-userscripts/releases - doesn't define releases
- https://github.com/xojs/xo/releases - defines releases & default assets
- https://github.com/Maximus5/ConEmu/releases - defines releases & includes extra assets
The zip is downloaded using the api, so the file name may or may not include the last tag associated with the commit.
See issue #62.
