Here is a patch so that if you run kppp and it is already running, it will be 
brought to the foreground. It only wants one instance to run at a time so it 
makes sense that it is a KUniqueApplication

It appears to work, and the UI behaves just fine, but as soon as you click the 
"connect" button kppp freezes. Is there a reason that kppp can't be a 
KUniqueApplication?
