initial work on WinRS datasources with multiple counters per command
fix typeperf -sc1 strategy
add zInterfaceMapIgnoreNames to zprops that are pass down
work-around the fact that IPEnabled is not declared as a boolean type in the XML returned, by comparing to string true
implement parsing of powershell get-counter with counter array. don't group by datasource counter, so multiple counters are sent in one command. group by strategy so collect method is simplified.
change source type selection from Single Counter to WinRS in objects.xml
