New version of polarpersonaltrainer supported

Polar introduced new changes to their exported files.

Now Sportaxy can extract these new file format and process the heart rate and elevation.
I also asked polar to add latitude and longitude to these files so that the position on the map can be tracked.

Here is how it works:

I. Extract an xml file from polar

II. Upload the xml file to Sportaxy and add workouts

III. Open the created event and click on "View" button

IV. See you heart rate and elevation. I hope polar will add latitute/longitude soon.
