Update package.json template to reference es5-shimify instead of es5-shim

Setting up a new project with spine.app I was getting an error because es5-shimify was not installed as referenced in lib/setup.coffee and slug.json. I updated the reference in the package.json template accordingly.

Was this change correct or should lib/setup.coffee and slug.json be referencing es5-shim instead?

Also bumped up the version numbers in the package.json template.
