New 'ubuntu-changes' script on drescher

[Colin Watson]

I hacked together a quick script this evening to display the Ubuntu
changelog entries for a package since the last Debian version. It's
installed as ~lp_archive/bin/ubuntu-changes on drescher, and also
attached to this mail.

I find this useful when doing syncs: you can run 'ubuntu-changes
PACKAGENAME' to display the changes that should have been integrated in
Debian if the sync is to be allowed.

Cheers,
