CWndBase更新至v0.1.6

//========================================================================
//TITLE:
// CWndBase更新至v0.1.6
//AUTHOR:
// norains
//DATE:
// Saturday 12-January-2008
//Environment:
// VS2005 + SDK-WINCE5.0-MIPSII
// EVC + SDK-WINCE5.0-MIPSII
//========================================================================

v0.1.0版本见:http://blog.youkuaiyun.com/norains/archive/2007/11/10/1878218.aspx

相对v0.1.0版本,有如下变动:
1.创建窗口时将WS_VISIBLE属性换成WS_TABSTOP,因为并不是每次创建的时候都需要显示
2.修正采用该类创建子窗口的bug
3.改进在非主线程中也可正常创建窗口.

关于第三点,只需要在调用Create()函数时,将bMsgThrdInside形参设置为TRUE即可.
