Qt: re-order GUI code

- re-order Qt Actions and connect() calls to match the real GUI layout,
  which makes things easier to read and understand
- remove signMessageAction and verifyMessageAction from tabGroup as we
  didn't use them anyway (as tooltips are not displayed in the menu remove
  these too)
- update 2 comments
