bug of TlsTunnelBuilder.java

[xiang20140619]

Socket makeTunnel(String host, int port, String proxyUsername,
String proxyPassword, InetSocketAddress proxyAddress) throws IOException {

  String proxyHost = proxyAddress.getAddress().toString().substring(
                0, proxyAddress.getAddress().toString().indexOf("/"));

shoud be:

        String proxyHost = proxyAddress.getAddress().toString().substring(
                proxyAddress.getAddress().toString().indexOf("/")+1, proxyAddress.getAddress().toString().length());
