useAccountManager popup improvements

[am-maneaters]

Few ideas I had for improving useAccountManager, mostly when using popup.

• improved status checking

  • check if popup window is currently open
  • something like const {popupOpen: boolean} = useAccountManager() for example: this would make it easy to display a loader on the base website while the authentication is happening in the popup window (i.e. {popupOpen && <Loader/>})

• callback events

  • something like useAccountManager(options, onAccountAdded : () => {}, onAccountRemoved: () => {}, onAccountsUpdated:: () => {}, onAuthCancelled: () => {})
    ex: in table editor, after authentication is finished, i want to use a callback to execute some cmds. here's how i do it now:
