proxy arg not working

[ssddOnTop]

When I try to add the arg --proxy-server='http://0.0.0.0:8080;' it doesn't seem to go through the proxy
however chrome --proxy-server='http://192.168.12.11:8080;' works without any problem

--proxy-server='http://0.0.0.0:8080; will not work perhaps for two reasons: 1) 0.0.0.0 is not a specific IP address, i.e. no local proxy can run on 0.0.0.0 to my knowledge; 2) I am not aware that a semi-colon is expected after the proxy-server argument.

I have personally tested that the following works, as you build the BrowserConfig:

config = config.arg(format!("--proxy-server=http://192.168.12.11:8080"));

What definitely does NOT work is proxy authentication, which is Chrome's fault, see my request #250
