Ubuntu (and others) dropping python-xml

[Andreas Wagner]

Hi,
when trying to understand a bit more about the dependencies of referencer I came across this 
ubuntu bug:
https://bugs.launchpad.net/ubuntu/+source/elisa/+bug/199014

In short, they are going to drop python-xml from the distribution and recommend to either drop 
python-xml as an explicit build dependency and rely on the core python package which by now 
includes much of the functionality, or use python-lxml (,or finally to include the needed 
functionality with your own package, but I'm not sure I got that right).

Can you check and adapt referencer to that (and/or change the development page 
(http://icculus.org/referencer/development.html) to reflect the new dependencies)?

Thanks,
Andreas
