Style dashboard

1. Added plots to Dashboard that show the rollup of a users allocation information for all providers.
2. Added "Calls to Action" to the Dashboard - pulled from Arturo.
3. Replaced all placeholder images with Gravatars.
4. Added CryptoJS for client-side hash calculations.  Properties like alias_hash don't belong in the API, so I'm pulling in Crypto to calculate those on the client side.  The inclusion of the alias_hash fields in the API appear motivated by a pure client side concern, especially since they're only there to generate gravatars for the client side.  So I'm making in an official client side concern.
