contrib/paclist: list packages installed from given repo.
The paclist script provides a simple method for monitoring which packages
are installed from a given repo. This is particularly useful when using a
testing or unstable repository.
Thanks to Allan McRae for the idea and an initial bash script. As suggested
by Dan, I tried to rewrite in perl, and this resulted in much better
performance. Then Dan further cleaned up the script.
