This PR implements the functionality discussed in #66. For the sake of not breaking things I added tests for the lockfile creation. I tried to replicate the testing framework used for https://github.com/greenkeeperio/greenkeeper, however I'm using sinon to stub and spy all the exec calls. I'll happily replace that with another solution that you prefer. Looking forward to getting some feedback on this :)
