Add a DaybedStorage PoC

Lots of things to change before it works:

 - [ ] Add daybed.js and hawk.js to vendors
 - [x] DaybedStorage is promise aware, I don't know how to get it integrated with react and getInitialState.

Hope @n1k0 can help me on this.
We might want to handle this on the application level.
One of the thing we wanted was to use localStorage and be able to trigger a remote load/save.
