设计一个Typecho访客统计插件，命名为"VisitorLogger"（访客日志）。这个插件会记录访客的详细信息，并提供后台管理功能。

VisitorLogger 插件方案

1. 插件目录结构

VisitorLogger/
├── Plugin.php                # 插件主文件
├── install.sql               # 安装SQL文件
├── uninstall.sql             # 卸载SQL文件
├── Update.php                # 升级处理
├── /widget/                  # 后台管理组件
│   ├── Admin.php            # 后台管理页面
│   └── Stats.php            # 统计功能
└── /views/                   # 视图文件
    ├── logs.php             # 日志列表视图
    ├── stats.php            # 统计视图
    └── settings.php          # 设置视图

2. Plugin.php 主文件
