Avoid timeouts during testing with the GUI in the devbox

[alberto56]

Every time tests are run, we get something like: Gateway timeout.

http://www.codetweet.com/nginx/solved-504-gateway-timeout-error-in-nginx-web-server/ solves it. We should implement that for the development box.

You just have to do a "sudo service php5-fpm restart" for it to take effect
