nginx: import from packages, add myself as the maintainer

This adds the nginx package from the old svn package fee. I adopt
the licensing information and will maintain the package in the future.
This request also updates nginx to the last stable version 1.4.7. It further
adds support for
 - naxsi (the ngix web application firewall)
 - syslog module
 - http upstream check module
 - support for the haproxy Proxy Protocol (this way nginx can see the real
   ip address behind haproxy)
Building was tested with target x86_64, ar71xx and avr32.
