Create a tag/release

[brockboland]

I just noticed the comment in sisyphus.js indicating that it is now version 1.1, but there aren't any tagged releases. Could you create a 1.1 tag? This will be helpful, too, for people who want to make use of this library at a specific version (such as this Drupal module).

Just created them, thanks for pointing this out.
