Get generator template package.json updating automatically

[gigabo]

We keep forgetting to update its deps during deployment.

Maybe we can use Asini's configurable package locations to get it updating automatically?

Born from this.

@gigabo can't we use something like Greenkeper? In the docs from asini they also recommend to use it to keep all the dependencies up to date (see this)

Good thought @rodrijuarez. The package.json this ticket refers to is actually a template that's used by generator-react-server. It lives way down in a nested directory where greenkeeper can't see it, unfortunately.
