RA2 and any mod requiring pak files will not download on fastl

[JustinBenedick]

After some testing it was determined that rocket arena 2 (arena) mod would not work unless the client already had the pak files download. The files would download from the server but very slowly. Not sure if issue starts at the server config for arena or how its setup on the fastdl server. At the very least we need example config set.
