Removing the release-stopper keyword from "topics", because:

Some basic work for grml-ppc has been done. But as long as I don't have at 
least another ppc system for developing besides my efika-board I don't think I 
can provide a high quality release of grml-ppc. Deferring the release 
therefore, I plan to release grml, grml64 (and maybe even grml-small) soon and 
will continue to work on grml-ppc later on. If you know any further 
possibilities how I could get access to ppc systems please let me know.

Any help, feedback, ideas,... welcome of course.
