APT based installer using PackageKit's session DBus API

 Sessioninstaller allows applications to easily install additional software
 (e.g. extensions or GStreamer codecs), uninstall files and perform simple
 software status queries by implementing the distribution neutral
 D-Bus session interface of PackageKit.
 .
 The whole process including confirmation, error reporting and progress
 and notification is handled by sessioninstaller.
 .
 The reference implementation of the D-Bus interface can be found in
 gnome-packagekit. It was also adpoted by KPackageKit.
 .
 In contrast to gnome-packagekit and KPackageKit it doesn't use the PackageKit
 daemon for querying and installation, but instead makes use of APT and
 aptdaemon (alternatively synaptic can be used).
