发个python2.6+wxPython+wxGlade实现的简单telnet客户端

    这些日子在公司测试机顶盒游戏，每次启动游戏的时候都要在windows黑色的dos窗口输命令，非常不方便，于是借着自己刚学的一点点python+wxPython的知识，写了这个telnet客户端，功能比较简单，根据需要可以再作修改。界面用wxGlade生成,本来我不喜欢wxGlade的,觉得不是很好用，但用着用着发现其实还不错，生成的代码也很容易和自己的代码结合。
    输入指令的输入框有默认的指令提示，为了方便写了个COMMAND指令列表,这是公司里用的,可以在源代码中COMMADN列表中修改自己需要的指令,或者去掉COMMAND,直接往输入框输指令。
