REDSOCKS2

This is a modified version of original redsocks. The name is changed to be REDSOCKS2 since this release to distinguish with original redsocks. This variant is useful for anti-GFW (Great Fire Wall).

##Note: Method 'autosocks5' and 'autohttp-connect' are removed. To use the autoproxy feature, please change the redsocks section in configuration file like this:

redsocks {
 local_ip = 192.168.1.1;
 local_port = 1081;
 ip = 192.168.1.1;
 port = 9050;
 type = socks5; // I use socks5 proxy for GFW'ed IP
 autoproxy = 1; // I want autoproxy feature enabled on this section.
                // The two lines above have same effect as
                //    type = autosocks5;
                // in previous release.
 //type = http-connect;
 //login = username;
 //password = passwd;
}
