Bring font-awesome.css in-package

[ocdtrekkie]

Privacy Badger detects one outside call in your app to netdna.bootstrapcdn.com, which seems to be for font-awesome.css, which really should be inside the app package and not brought in from an outside source. Note that while this works right now, eventually client-side sandboxing in Sandstorm will break this existing setup.

Allegedly the official fontawesome package, at https://atmospherejs.com/fortawesome/fontawesome should be built-in.

It seems the natestrauser version is basically just "fontawesome at a CDN", which Sandstorm packages should avoid: https://atmospherejs.com/natestrauser/font-awesome
