Fixes#151
- Cancelling or completing a tx now goes back to account detail view.
- Restoring a vault now does not select an unloaded account, shows account list.
- Account list now never selects an item only uses the cells as buttons.
- 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.
