Get latest versions of dependencies

GET http://registry.npmjs.org/-/package/{{dependencyName}}/dist-tags

This GET request fetches the latest version of the specified dependency from the npm respository and compares it with the current version of the dependency.

If an update is not required, it moves to the next dependency.

If an update is required, it moves on to creating a pull request.

This currently works on the public packages only.
