Fix And Optimize

[WhaleFell]

This is a fixed version of the original project, mainly fixing the following issues:

1. Update the runtime environment to Python3
2. Fix cms recognition
3. Fix port scanning
4. Fix the original author's shitty code

Why fix it? Because I received a graduation design from a 985 University Cybersecurity student on an slavery platform. He gave me money, so I fixed it.
I didn't expect a stupid college student to help a top university with his graduation project!

I hope original author can merge this PR. thx very mush!

这是个修复版本, 主要修复了以下问题:

1. 更新运行环境为 Python3
2. 修复 cms 识别
3. 修复 端口扫描
4. 修复源作者屎山代码

为什么要修复呢? 因为我在外包平台接到一个 酒吧舞网络安全学生 的毕业设计. 他给钱, 我就修复了. 没想到一个文盲大专生也配帮顶级大学做毕设.
