Updated imagemagick packages fix security vulnerabilities

Updated imagemagick package fixes security vulnerabilities: The OpenBlob function in blob.c in ImageMagick allows remote attackers to execute arbitrary code via a | (pipe) character at the start of a filename (CVE-2016-5118). Integer overflow in MagickCore/profile.c (CVE-2016-5841). Buffer overread in MagickCore/property.c (CVE-2016-5842). Also, several packages have been rebuilt to use the updated Magick+±6.Q16 library. These include converseen, cuneiform-linux, inkscape, k3d, kcm-grub2, kxstitch, performous, perl-Image-SubImageFind, pfstools, pstoedit, pythonmagick, synfig, vdr-plugin-skinelchi, and vdr-plugin-skinenigmang.
