Ingo Weinhold 796343ed73 Allow specifying the compression level for package creation
* Introduce BPackageWriterParameters which comprises all parameters
  for package creation, currently flags and compression level. Such an
  object can be passed to BPackageWriter::Init() and is passed on to
  PackageWriterImpl and WriterImplBase.
* PackageFileHeapWriter: Add compressionLevel property and pass the
  value on to ZlibCompressor.
* package add/create: Add options -0 ... -9 to specify the compression
  level to be used.
