Integrate github with moodle plugins directory

A lot of developers use github to distribute/develop their plugins. It will be great to see github completely integrated with our plugin repo.
Suggestions:-

1. Plugin version should be parsed using $plugin->version in version.php
2. Plugin compatibility with moodle should be parsed using $plugin->requires
3. Keep copy of all versions of the plugin with their compatibility unless explicitly deleted by the developer
4. Automatically build download zips from Github url
5. Keep support for existing manual upload of zips
6. Also a more strict format of readme should be recommended

I would be more than happy to provide more feedback if needed.
Thanks
