Site update

Hi everyone,

I updated the site to have a link to apachecon amsterdam and messed up the style of the site :(.
By accident I committed a local change that shouldn't have ended up in subversion.
All fixed now, waiting for it to become live (just update /www/jakarta.apache.org on people.

I also fixed the mail2.html, where all links were broken (archives were all pointing the
mail-archives.eu.apache.org which is kind of broken :)

Mvgr,
Martin
