[Feature Request] Add autocomplete to the editor

[zhuangzhuang]

Is your feature request related to a problem? Please describe.

1. 这tmd也太大了, 能精简还是精简下
   

2. 去掉ace支持, 已经用了微软的 monaco package里就不要在ace了

3. 加点自动补全吧, 已经有大微软的moaco支持, 在上面加个补全不就是分分钟的事.
   可以参考 https://playground.babylonjs.com/ 也是支持线上javascript编辑的, 然后自动补全的
   具体用法就是编译出 .d.ts文件 然后
   https://github.com/BabylonJS/Babylon.js/blob/master/Playground/src/tools/monacoManager.ts#L373
   就可以了, 顺便类型上加下函数说明吧, 自动文档也有了
   (ps: package依赖实在太大, 下了半天下载不下来, 不然我就提交pr了)
