Unity Editor工具，导出unitypackage可选择是否包含脚本

概述

Unity自带的Export Package...功能，如果选中资源中包含脚本，或者Prefab挂载了自定义的脚本。在之后弹出的选择框内，如果勾选了Include dependencies会将整个项目所有的脚本全部都包含在内。等于导入了很多不相关的代码。如果取消勾选Include dependencies，又只有选中的那个资源，其他引用到的资源又不包含在内。

但是在实际的工作中导出资源时，只想导出跟选中资源相关的资源，并不想包含脚本，或者仅包含该prefab挂载的脚本。这时候就需要自己编写一个Editor工具实现该功能。具体的代码如下
