qapplication_win.cpp update

Hi all, 

In the setMainWidget function... instead of setting the caption to the 
application name
main_widget->setCaption(mwTitle); 

shouldn't it check whether the main_widget has a title first?
if( main_widget->caption()->isEmpty() )
 main_widget->setCaption( mwTitle );

Just my thought...

Warmest Regards,
