swap store for store2

[joshua1]

Hi @ropbla9 can this be extended to swap store for store2 which is a more advanced local / session storage api. It should also be possible to add values to localstorage without having to list the variables in the array and still have them reactive just like observables? I am looking to try something like that, will do a PR if it works

@ropbla9 The master branch for this project doesn't depend on store2 and still requires you to list the items you want to expose. Am I missing something?
