GPII-547: Created "accountCreated" in GPIISession.
The PMT frame hooks to this event to show user token notification.
Made the login/logout calls of GPIISession non-async because we want to serially streamline the logout/login that is triggered by the GPIIStore "refresh" of system level applications when setting preferences. Does not affect much the Ux (at least when running GPII in localhost).
In GPIIStore, when saving preferences of existing user, thus NOT creating new user token, log the user out and then immediately login again in order to "refresh" the system-level applications with the new saved preferences.
GPII-547: Removed the "args" property whenever it contained only {arguments}.
GPII-547: Corrected some comments.
GPII-547: Refresh of AT applications is happening with an event.
GPII-547: Created some TODOs.
GPII-547: Moved logic of success event of set to external function.
GPII-547: Getting logged user's token from GPII.
Merge branch 'master' into GPII-547

It does not contain it anymore as changed in GPIISession.

GPII-547: Exposing getLoggedUser success/error events.
GPII-547: Better wiring of events/listeners/invokers/functions.
Also used more intuitive naming.
GPII-596: Giving focus to magnifier's ON/OFF onDomBind.
Had to re-find the DOM element for this to work.
GPII-596: Giving focus to magnifier's ON/OFF on value change.
Problem is that now focus always lands there when the PMT starts.
GPII-596: Binding to valueCheckbox's change event for focusing.
