earlier detecting some/expected problems when using PAC files (not connected to corparate network)

What steps will reproduce the problem?
1. setup a proxy in IE, that doesn't exist
2. use proxy vole
3.

What is the expected output? What do you see instead?
- Less LOG output

What version of the product are you using? On what operating system?
- Windows, (latest release) 2012-12-03

Please provide any additional information below.

- If you have a proxy, which I normally have when connected to the Corporate 
Network
- proxy-vole writes a lot of output
- So the process can be "aborted" earlier

For example if you get: 
- UnknownHostException, get out "early", and use fallback
- If the content of the PAC file is empty, get out "early", and use fallback

I know this is a small enhancement, but I'm always "annoyed" by "unnecessary" 
messages in the errorlog file...

"unnecessary" messages, will lead to "cry wolf", and at the end the missing 
*real* error messages.

Here is the log output...
