QT---Native Wifi functions 应用(WiFi有密码连接)

实现功能
    无线网卡列表
    无线热点扫面
    无线连接（有密码，配置文件连接方式）
    无线断开
    重命名本地无线名（两种方式）
    删除无线配置文件
    开启和关闭无线网卡
Native Wifi 简介
    是提供给软件开发者来开发windows 无线管理的一系列API。编程人员可以通过这些函数来进行相关的无线管理，当然我们还可以通过netsh终端命令来管理，这对于非编程人员就可以简单的实现，具体可以查阅相关资料去了解。
    API如下：
无线的连接相关知识
    从windows的无线网络属性设置窗口来对比，在API编程中，同样有个配置文件来设置这些属性的，那就是profile文件，通过编写xml文件来设置相关属性。

WLAN_profile Schema Elements [xml配置文件编写格式]：

    

Wireless Profile Samples[无线配置文件例程]

    例如常见的路由器，安全类型为WPA2-PSK的xml配置文件如下（有密码）：
    
<?xml version="1.0" encoding="US-ASCII"?>
<WLANProfile xmlns="http://www.microsoft.com/networking/WLAN/profile/v1">
    <name>SampleWPA2PSK</name>
    <SSIDConfig>
        <SSID>
            <name>SampleWPA2PSK</name>
        </SSID>
    </SSIDConfig>
    <connectionType>ESS</connectionType>
    <connectionMode>auto</connectionMode>
    <autoSwitch>false</autoSwitch>
    <MSM>
        <security>
