* added class BPackageInfo, which contains packaging attributes of a package (the values relevant for package management) * implemented parser (mostly) for reading a BPackageInfo from a config file (.PackageInfo) in order to pass them on to the PackageWriter when creating a package * pulled hpkg-related stuff from bin/package into the package kit * adjusted packagefs-Volume to skip .PackageInfo files when populating the mountpoint, as those files shouldn't appear as part of an activated package git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40301 a95241bf-73f2-0310-859d-f6bbb57e9c96
