Some improvements for installation of binary packages.

* If any dep of a package cannot be found in the repository pool,
  show it on xbps-bin.

* Add the automatic-install boolean obj into pkg's dictionary
  on regpkgdb.plist, this will be used to implemented something
  like "apt-get autoremove".
