Fixes to my fixes of BView::MakeFocus(), the previous focus BView needs to be unfocused of course so the derived classes implementation gets called. Simplified BWindow::setFocus(). BView calls FrameResized() and FrameMoved() if it has no parent, I don't know how R5 handles it, but I added a TODO...
