Kover 6

After having successfully updated libcdio in rawhide to 0.90 and also introduced the split off libcdio-paranoia in Fedora's development branch, I rebuilt most of on libcdio depending packages. Two packages were no longer building but their maintainers quickly fixed it. The only broken dependent package was kover. As I am still upstream of kover I had to change the code to use the new CD-Text API of libcdio 0.90.

With these changes I have released kover version 6 which is available at http://lisas.de/kover/kover-6.tar.bz2.
