Integrating js-gardener?

[simlu]

This repo is becoming a central dependency for us. I was wondering if you would accept a pr integrating js-gardener?

I would do all the leg-work, but you would still need to configure the badges (travis, greenkeeper, semantic-release, etc - this is not a lot of work as you don't need to touch config).

Please let us know. Cheers, L~
