* do not rely on /tmp. BTW I tried the redirect of stderr thingy to get dialog
selection into variable without temporary file but that did not work: dialogs
were not displayed anymore.
* cleanup menuitem to avoid confusion
* SelectSuSudo stores selection in SuSudoSelection and does not open dialog in
case SuSudoSelection is already set
