Update for ImageMagick, ImageMagick.256, Mozilla... recommended
Tolerate tilde in package version. This allows building packages which use the tilde to indicate a pre version.
Note: zypper will not handle tilde in 11.4, '1.0~rc1' is seen as newer than '1.0'.
Handle also /etc/alternatives properly to fix buildfailures which happen with some newer packages.
