Proxyusr+Proxypas abbreviations are less readable

[JeremyRand]

The Proxyusr and Proxypas abbreviations ( https://github.com/robertmin1/heteronculous-horklump/blob/fe0fa005b074e0464c856940333eee02e874ae57/main.go#L80-L81 ) are somewhat nonstandard and difficult to read. I think expanding to Proxyuser and Proxypass would be more readable and more in line with standard convention.
