Cocos Creator 使用protobuf

protobuf.js 5.x 異步加載方式：

var ByteBuffer = require("bytebuffer");

var ProtoBuf = require("protobuf");

cc.loader.loadRes(path, function (error, content) {

var Builder = ProtoBuf.loadProto(content);

var Data = Builder.build(str);

var data = new Data();

data.setLoginType(loginType);

同步加載方式需要修改源碼：
