Title: Export `Store` as default from ./system/store

This allows it to import it simply via `import Store from
"./system/store"` instead of `import {Store} from "./system/store"`.

Another option could be to move the `PromiseArray` and `PromiseObject`
definitions in `system/store.js` to `system/promise.js` and import them
accordingly.
