Subject: [PATCH 3/3] Allows automatic cleanup of updated packages data

When a package is upgraded, its old installation scripts and list
of files are kept under /var/lib/pkgtools. This commit implements
the function to remove those lists and scripts, the variable to
govern its behaviour and the documentation about it.
