去掉chrome开发者提示

对于有强迫症的程序员真是难受，不仅是中国，国外的码农呼声更高。

脚本来源https://sourceforge.net/projects/devwarningpatchgen-bat/

直接浏览代码https://sourceforge.net/p/devwarningpatchgen-bat/code/ci/master/tree/DevWarningPatchGen.bat

这个脚本是一个国外大神写的。亲测78.0.3904.97（正式版本）（64 位）版本，试了有用，以前都是用反汇编找字符串，没想到这个更简单，神奇。

有同学反映80版本不行，我建议是降版本。这个批处理也好久没更新了。

把以下代码新建文本保存为 bat脚本，管理员运行就OK了。

已更新至2020-3-2版本
