ButtonEvent为NSIS自定义按钮提供增加响应函数代码功能

/*
 ButtonEvent为NSIS自定义按钮提供增加响应函数代码功能
 *可以使用resourcehacker对对话框资源进行更改,ButtonEvent插件不提供动态插入按钮功能,
 资源UI在NSIS安装目录下的ContribUIs里面,MUI:modern.exe,Classic:default.exe.
 *你可以使用如下语句进行引用:
 *(MUI/MUI2)!define MUI_UI ui_file
 *(Classic)ChangeUI all ui_file
 *在添加按钮资源的时候,尽量将控件的ID予以命名在nsis中自定义控件是从1200开始的,如果不对控件进行命名,
 在对控件进行处理的时候比较麻烦,比如难以知道其句柄值.
