Oliver Tappe 33bc4425be Largish adjustments to PackagerReaderImpl and package attribute
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)
