Vadim Zeitlin 3d9656395a Fix unwanted message boxes in widgets sample once and for all 
Add IsUsingLogWindow() that can be used to check if the log messages go
into the listbox instead of being shown in a message box, which was
annoying when starting or quitting the sample.

This is a bit more complicated than the hack previously used in
TextWidgetsPage::OnText(), but more general and can be easily reused for
the focus loss messages, for example.
