ConsoleWindow中的双击日志定位

    很多项目都有自己重写Debug.Log的习惯，难免会遇到在Unity的Console窗口中双击日志， 但是没法直接跳转到想要看到的代码那一行的时候，解决办法有以下2种：

1. 将自己封装的日志类制作成DLL再导入到Unity使用，但是有时候想修改日志类的代码却比较麻烦了～～
2. 使用本文提供的LogEditor类来自动定位！。！下面来详细说明下该类吧～～

使用方法：

1. 将LogEditor类的脚本放到名字为Editor的目录下(如果没有Editor目录就新建一个吧)
2. 在这里修改和添加自己封装过的日志类(路径+类型)，支持添加多个封装的日志类
