Add parsing for PAC result strings -- ProxyInfo::UsePacString().

Added the support class ProxyServer to avoid losing the proxy server's type information (http, socks) when populating the list.

The format of the configuration strings has been extended accordingly to include an optional [<scheme>"://"] prefix.
(i.e. "http://", "socks4://", "socks5://").
