fixes 413 checkout deleted package

* altered command do_checkout
  new option -D | --deleted. Can only be used with PACKAGE and needs
  -o to work

* what happens:
  core function checkout_deleted_package fetches the file list of the deleted
  package and saves it to given destdir. If destdir is not existent it
  creates the destination directory. Otherwise the files will be written
  in the existing directory.
