This is a medium task.

In a previous task the functionality was added to Create and Delete a Placemark.

However currently the created KML code doesn't pass

Modify the C++ code so that KML code created via the TourPanel and its Add/Remove Placemark feature passes the validator (in terms of the AnimatedUpdate code - other errors that are not related to the Tour can be ignored).

Additionally the same code should also make the placemark (and its balloon if enabled) show up in Google Earth.

Please also change the code of the latest bestofosm kml file accordingly.
