Add a DaybedStorage PoC

Lots of things to change before it works:

 - [x] 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.
Lacks one level : a list has an "itemtype", which in this case would be "object", and its parameters would have those "fields". I don't think this definition is valid at all.


```
{name: tasks,
 type: list,
 itemtype: object,
 parameters: fields: [...]
 }
```

Which makes me wonder one thing : why the h**ck didn't I design the ``list`` field using a single "item" property : 

```
{name: tasks,
 type: list,
 item: {
    type: object,
    fields: [...]
 }
```
