This script runs through /usr/lib and /lib and tries to find all libraries which are no longer being used and more and deletes them.
This will help us to free space on root partitions that are limited to 2GB.
However, the script does not cover 100% of the cases, so that some files still need to be deleted manually (e.g. boost with their weird versioning schema).
This script should be executed after a Core Update has been installed.
