handling: * package attributes are now compatible with the low level attribute handling of other HPKG attributes (such that 'package dump' now shows package attributes, too) * dropped type names from hpkg format, the attributes were identified by IDs already and this simplifies the code considerably. Type names are now handled in BLowLevelPackageHandler only. * instead of rolling their own mechanism, high-level package attributes handling is now implemented via a corresonding set of AttributeHandler-subclasses * adjusted package writer to only write package attributes that are needed (empty ones are left out) git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40466 a95241bf-73f2-0310-859d-f6bbb57e9c96
