Correct IPv6 nginx error

I removed the "fix" where the IPv6 listener wouldn't conflict with the default nginx listener.

I believe that the Internet needs to be IPv6-ready, so I made this minor change. All sites will now be able to listen on IPv4 and IPv6. I think this also fixes issues with Debian wheezy (which doesn't need dotdeb, btw).
Added version autodetection for dotdeb-source
