Starting First Python Transition

[Scott Kitterman <debian@kitterman.com>]

I just uploaded python-defaults to Unstable that drops Python 2.5 and adds 
Python 2.7 as supports Python versions.  Python-central, distribute, and 
python-stdlib-extensions are already updated to support Python 2.7.  The 
planned python-support upload later today will complete having the core Python 
infrastructure updated.  

Once this is all installed in the archive, we'll start doing selective binNMUs 
to drop 2.5 and add 2.7 where they won't affect other transitions.  There are 
also affected arch:all packages that will need uploads to update.  The 
transition tracker for this transition is at:
