update.py: Python version verifcation ?

[miroi]

Hi Rado,

would it be please possible to add Python version verification for update.py ?

It's more convenient to have Python version requirement explicitly typed in the screen when lower version of Python is used.

I agree with you Miro - I will implement that.

This is now done for Python 2.6. Python 2.4 will still throw an ugly message because of with. It would need restructuring the code to remedy that which I will not do for the moment.
