Tor Browser needs an "Automatic Proxy Configuration Script" option

Some TBB users need to configure proxy with a PAC file instead of standard host+port configuration.

The current Tor Browser proxy configuration gives no option to these users, as they can configure only a fixed host and port pair of options, and most users are unable to extract these from the pac file (provided they are able to download and open it).
