[aur-general] Delete package "ogrenewt-cvs"

Hey, please delete package "ogrenewt-cvs" in AUR as its purpose has been lost long ago when Ogre switched to SVN. Right now, OgreNewt isn't even being maintained in the Ogre SVN and now uses its own hosting. Additionally, the "OgreNewt" AUR package already takes care of the stable version. -- Sven-Hendrik
