Power value from Suunto .gpx file and fix with unvalid 0m Altitude in .tcx

This week I noticed that Suunto http://www.movescount.com has updated their Export functionality.
The .gpx file contains now Power values, it is named "gpxdata:power" an not as I first expected bikepower.
A .tcx files is now available as well which contains "Watts", but there are lots of 0 "AltitudeMeters", that's why I adjusted the tcx Parser as well.
The new .fit file has a lot more problems, I better wait, maybe Suunto will change it anyway.

If you like, I send you some sample Files.
