Sometimes you want stale data right away, then refresh it async. This adds `findStale` to the store for that case. If it returns an object with `hasResults` you can get the `results` and display them. It also returns a `refresh()` method to freshen up the stale data. To enable `localStorage` support for stale data, just include the mixin `StaleLocalStorage` into an adapter for that model. This commit includes a sample of doing that for `Notifications`.
