Update to track name change of the env module.

The env module has gotten a new name (previously environment),
which means that this module needs to change its reference to
one of the classes from there, as well as update the README to
refer to the proper module name.

While doing that, also insert the repo URL for the env module
in the README (there wasn't even an incorrect one), update the
copyright year and fix a typo.
