Nginx install page (thanks Jacob Clark)

This is a patch to create documentation for Nginx 1.4.x on Unix systems,
it covers the build of PHP and Nginx and configuration with PHP-FPM.

Hopefully this will documentation will help create a more 'standard' way
to configure Nginx, something I feel is much needed by the php
community.
