VEH-10: Check Framework's IP source

method getip has been adjusted, but changes haven't yet been tested

Added IP check to test submodule. Unfortunately it's returning the IP of the proxy, so need to identify why.

Headers are

Don't want to rely on the X-Real-IP as that's something NGinx has been configured to send.

The keyname used with $_SERVER wasn't prefixed by HTTP_.
