New Version Please

The --stdin flag that was added recently is a really important feature so it would be nice to have a new version released with it.

By "really important", I mean it's absolutely needed to be able to integrate htmllint with text editors/IDEs.

@mlochbaum Could you provide the npm access for us? We can upgrade by ourselves.

Thank you
