Now you have no excuse not to upgrade to CEGUI 0.5.0

I wrote a python script to upgrade layout files to the new Unified Coordinate System. It is available on the wiki: http://www.cegui.org.uk/wiki/index.php/CELayoutUpgrader
The code is GPL, so feel free to make modifications and release them.
Enjoy.
P.S. would be nice if someone ran py2exe to package it up nice for windows users.
