[EuroPython] website localization to german .. first steps

[Thomas Reulbach]

I translated index, header, footer and contact page to german as a 
beginning and will continue if nobody opposes.
If you want to change it just give me a hint or change or undo if you don't 
like something.
The Localizer product really made translation a lot easier for me than I 
was used to before.
If you see another priority for the next translating steps just let me know.

Kind Regards
