Make account detail view the primary view

 - When unlocking, the first account is now selected by default and displayed as the main view.
 - There is now a "CHANGE ACCT" button on the detail view to show the accounts list.
 - Clicking an account from the accounts list now navigates to the detail view and selects that account.
 - Config/Info screen "back" buttons now fire a new action, `GO_HOME`, which is configured to navigate to the accountDetail view, putting that logic in one place.
 - When locking and unlocking again, the first account is always displayed, eventually we should persist the selection.
