don't check whether the window is shown and enabled in AcceptsFocus() itself

as it makes overriding it in derived classes problematic; provide a separate
non virtual CanAcceptFocus() method checking whether the window accepts focus
and if it can accept it now and use it instead of AcceptsFocus(); documented
AcceptsFocus() and AcceptsFocusFromKeyboard()
