Handle all the Node.js dependencies the same way

Add jshint as a dependency to package.json. Enforce minimum versions
for jshint and autoless.

Now everytime a Node.js Makefile task is run, it checks if the
dependencies are up-to-date and the versions can be updated easily for
everyone working on MobileFrontend.
