Title: update grunt-concurrent package

- without this update, an `npm shrinkwrap` of a package with `gruntfile-gtx` as a dependency (and a newer version of `grunt` installed?) will fail with the following:

It's a mystery to me why this would happen exactly, but the problem may be either the mismatched versions of `grunt-concurrent` in `gruntfile-gtx`'s deps/devDeps, or with `grunt-concurrent` itself.

Anyway, this fixes the issue.
