No Auto-Config URL only setting

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a proxy profile that only has the Auto-Config URL
2. You can't save the profile, so enter something into the "Port" field
3. Save, then Activate the profile

What is the expected output?
Be able to create a profile with Auto-Config URL only.
Be able to have profiles that do not activate the "Proxy Server" check box 
in the control panel if selected, but also change the automatic 
configuration script URL.

What do you see instead?
You can't leave the "Port" field empty.
"Proxy Server" check box is checked even though the "HTTP Proxy" field is 
empty.
