Currently, master's /lib still corresponds to 1.3.6, meaning that we can't use it to fix the focus issues on mobile.
In this commit, I just ran yarn in the repo.

This will make sure that master is directly usable from the repo with "react-currency-input": "git://github.com/jsillitoe/react-currency-input.git" in package.json.

Previous commits on master also fail on Travis so there is no reason not to merge this :-)
