Add bower.json so Lumenize can be installed as a bower component

I un-ignored the browser-ified files, and added a bower.json so this can be installed as a bower component. I kept the package private for now (so it can be installed from a git repo, but not registered with bower). You may want this to be automated more so that the versions are kept in-step with the package.json, another option might be a separate repository just for the build artifacts... this is just enough for our team to start using this as a bower component, which i needed for the current story :)
