New Launchpad feature: Diff between Sid and Oneiric

[Bryce Harrington]

There's now support in launchpad for displaying source package diffs
between what's in ubuntu oneiric and what's in debian sid.  Check it out:

This is an outcome of the Launchpad team's current 'Derived Distros'
development focus.  The primary objective is to make life easier from
people making derivatives of Ubuntu such as OEMs, but since Ubuntu
itself is a derivative of Debian, it looks like this is going to win us
some nifty new functionality too.  This includes a comment area to allow
packagers to mark merges they're working on or leave notes for other
packagers, buttons to make it easier to sync one or more packages
straight from debian, and functionality for derived distros to push
their changes back up to us more easily.
