Allow proxy for all ports of a domain

[RacingTadpole]

Currently if csiro.au is present in serverconfig.json's allowProxyFor, all domains ending in csiro.au can be proxied... but if an explicit port is appended (eg. ...csiro.au:80), it is not.
Is there a reason for this?

csiro.au:80 won't match unless the port is explicitly included in the URL. i.e. it's not smart, it doesn't know that 80 is the default. But if the port is included, I believe it will match *.csiro.au:80. Is that not what you're seeing?

[RacingTadpole]

Yes, but I'm suggesting we make csiro.au also match csiro.au:* (ie. not just 80 but also 8000, etc).

Steve made the same suggestion the other day. See discussion here:
TerriaJS/terriajs-server#13

And perhaps close this issue in favor of that one, because this is really a server issue?
