[VER] 0.3.5-alpha

[FEAT] 现在，我们的内置类型 Int, String等也有构造函数了！像是StructType一样调用，Int{10}
[FEAT] List,Map赋值默认为Alias, 现在，通过 List{other}/Map{other} 来创建新的container! 复制出新的容器
[IMPL] Object toString对于 String type 输出进行修改！
[IMPL] ... 还有一些忘记了！
[ALL] Happy new year! And hope Fig-lang become better! Let's build a new world!
