Added chrome.storage / additional login events / reactiveQuery sort, skip, limit options

1. Chrome storage: per previous PR
2. Login events: added loginAttempt (once a login attempt starts) and loginNull (if the user is actually not logged in) events
3. ReactiveQuery options:
    - sort : works with a single attribute only for now (can be a nested attribute)
    - skip : ok
    - limit : ok
