Luboš Luňák 854e9cc05a With windows that have are listed for the focus stealing prevention 
workaround, don't make their user timestamp newer than the active window's
one (unless a real user activity takes place in them).
As they are belong to the active application and just fail to say so,
this makes sure they won't prevent that application from getting focus
by having newer timestamp. E.g. Alt+F2, typing URL, kio_uiserver dialog
shows (has workaround), SSL certificate dialog shows (shown by kdesktop),
and it wouldn't get focus, because kio_uiserver's timestamp would be later.
