[Review] Request from 'schubi2' @ 'yast/yast-http-server/review_140916_virtualhost'

Please review the following changes:
  * caad591 packaging
  * ede2685 set VirtualHost in /etc/apache2/vhosts.d/<hostname>

Just to clarify my point, if ```value``` follows that estrange convention, ```item.has_key?("HostIP")``` will be always false.
