flyspray: add removed packages script

This script goes through all open bugs in the Arch Linux and Community
tracker and extracts the packagename from "[$pkgname]" and tries match
it to the list of packages in the repo. If there is no match the package
is assumed to be dropped from the repo and printed.

This script will give false positives, but not enough which requires
some extra filtering.
