Cleanup dependencies in package.json

[utvk]

Some of the dependencies in package.json, e.g. the babel deps, should probably be moved from dependencies to devDependecies?

Also: Do you use "karma-phantomjs2-launcher": "^0.4.0",? maybe remove if not in use?

I did move some devDependencies to dependencies on purpose to ease the building process for production deployment. If we move those back to devDependencies, then we can build the app on local and then deploy it. I don't know if that will cause issues on travis, I have not tried it. When I get the time, I will give it a shot and see what happens.

I am not using that launcher at the moment, so yes, it has to be removed.

Thank you for the heads up.
