Stop RPS from asking for <mac>.cfg and common cfg

[zirophyz]

Yeah, I reckon I am going about this wrong. I will just use my script to serve a file based on the request. So, if phone requests common.cfg, my script will pull that from a private directory. I will however, do a quick lookup of the MAC address to "authorise" that the phone is legitimate prior to serving any cfg files. Lastly, I'll encrypt the cfg files. So there'll be a few layers of security - a person would need to firstly spoof a known MAC (will take a while to brute force), and if successful in spoofing a correct MAC then they'll be served an encrypted file anyway.
