In this task

http://www.google-melange.com/gci/task/view/google/gci2012/7988214

the stars tool has been extended to display stars on a sky map theme such as:

devel-home.kde.org/~tackat/nightsky-marblemap.tar.gz

In this task a separate tool should be created that takes the marble/tools/stars/catalog.dat file and the file

marble/data/stars/dso.dat

as an input to create KML Placemarks  that represent the deep sky objects.

The same icons should be used that are used in the stars plugin. All objects should have labels.
