Darwin doesn't include username/password in proxy URL

[tstromberg]

Using head:

% go-get-proxied -j
{
   "host": "10.9.8.7",
   "password": null,
   "port": 31280,
   "protocol": "",
   "src": "State:/Network/Global/Proxies",
   "username": null
}

I have both set.

%  scutil --proxy
<dictionary> {
  ExceptionsList : <array> {
    0 : *.local
    1 : 169.254/16
  }
  HTTPEnable : 1
  HTTPPort : 31280
  HTTPProxy : 10.9.8.7
  HTTPSEnable : 1
  HTTPSPort : 31280
  HTTPSProxy : 10.9.8.7
  HTTPSUser : https
}

It looks like the password isn't exposed by this interface, but the username definitely is.
