Added post-installation check on __exit__ of archinstall.Installer(). This will 'verify' that the installation is complete after leaving the installer, or warn the scripter/programmer/user that there's steps missing in order to complete the installation. This is a step towards combating root being disabled and sudo users forgotten to be created - to avoid total account lockout.
