This patch enables modx revo to run on an arbitrary port (aka port-based
vhosts) behind a loadbalancer.  Explanation:

internet <--> haproxy 80/tcp <--> port-based website 8082/tcp

What this patch basically does it to convince modx port 8082 is the default
web server port thus no port information is appended to (dynamic) links.
