Title: Only escape necessary chars in cookie value.

I ran into the problem this patch fixes when using twill. A server was sending cookie's where the value was an equals (=) character. This caused mechanize to send an escaped cookie back to the server, which it was then unable to understand. So authentication failed.

Thanks!
