Define `provider("localStorageProvider")` and expose "prefix" and "cookie" as configuration options?

Wouldn't `angularLocalStorage.prefix` and `angularLocalStorage.cookie` be better served as configurable options on a `localStorageProvider` object? That would require a refactor from `service("localStorageService", . . .)` to `provider("localStorageProvider")`... If you'd like help with that, lemme know...
