[WINLOGON]

- Change state to STATE_LOGGED_ON_SAS while the security dialog is open.
- Ignore an SAS while winlogon is already in an SAS state.

[MSGINA]
- Read AutoAdminLogon and DisableCAD settings when msgina is initialized.
- LoggedOutWindowProc: Disable the Cancel button on the logon dialog if the DisableCAD option has been enabled.
- GUILoggedOnSAS: Fix misuse of result variable which caused some really strange effects.
