Login screen UX

[antirotor]

Problem

When AYON user key expires and "login" dialog is show, we should show directly password prompt because with this dialog you need to click on the right icon to get there. In most cases, you would need to log in again anyway.

Also "Logout" button is cofusing, because when this is shown, you are already logged out. It should have maybe "change user" and "exit" buttons.
