From: Matt Madia

* InstallOptionalHaikuImagePackage: Made the first argument an actual file
  name, i.e. the extension ".zip" is no longer appended by it.
* Renamed rules UnzipArchiveTo{Container,HaikuImage} to
  ExtractArchiveTo{Container,HaikuImage} and generalized them to support
  tgz/tar.gz archives (implemented in build_haiku_{image,cd}).
* Removed DownloadOptionalPackage. DownloadFile is used instead.
