I don't know how to pass Travis CI, I did run all tasks, and commited a build.

@artshevtsov Good catch. But please submit only your first commit (de0d95e) as a pull request. Do not submit dist folder or other unrelated files.

Done

Thanks. I'll have to figure out why Travis is failing. But that has nothing to do with your changes.
