[EuroPython] downloading the presentations..(poor default name)

[Simon Dahlbacka]

First of all, thanks for a great conference.

Secondly, I tried to download some of the slides for the talks, but
noticed that the browser provides a rather poor default name

Firefox gives download.cpy.pdf 
and IE gives download.pdf

..if I remember this can be fixed by adding a Content-Disposition header.
