Title: Optimize process listing for Unix without /proc (OS X)

Do not rerun lsof for known processes.
Instead look up "isQtApp" property in previous process listing if process was already examined.
Reduces recurrent process listings (but no the first) from about 50 seconds to about 20 milliseconds for me.
