Add localstorage to api

This consumes https://github.com/knadh/localStorageDB to implement a database query system on top of `localStorage`. Session data is now saved directly to `sessionStorage`
food for thought for later: I can see us making  `/data` directory somewhere, where we store all of this data.

```
/data
   - users.js
   - pages.js
   - whatever.js
```

Each of these are AMD modules that return this data. Then this file would load up all of our data sets and add them to the DB.
