[texworks] Ubuntu packages

[Karl Berry]

    under the instructions for Ubuntu installation, ...  I have built
    new packages, for Ubuntu intrepid and jaunty, which exist at
    https://launchpad.net/~agrawalr/+archive/ppa.

Cool.

I could update http://tug.org/texworks, but I'm not sure if I should,
since the build info is on http://code.google.com/p/texworks.

Perhaps Jonathan would be happy if someone else (Alain? David? Rohan?)
helped to keep that info up to date?
