Title: Include fontawesome on the list of assets to precompile

When you deploy to a production environment, using rake assets:precompile does not include the fontawesome files and backend icons on the admin side are not showing up.

I've only recently started using spree, so there might be a legitimate reason behind why it was left behind.

In any case, this fixed the problem for me.
