[EuroPython] Refereed papers track CFP

[Armin Rigo]

Hi Michael,

The Refereed Papers call for papers from last year (still showing on the
site as if it were for 2006) should be kept, with only corrections in
the dates:

22 April 2005 -> 5 May 2006
1 May 2005 -> 15 May 2006
1 June 2005 -> 17 June 2006

I've pushed the dates to be (relatively speaking) a bit later than last
year, because from last year's experience we don't need much time
between the full paper submission (3rd date) and the beginning of the
conference.
