- fixed build for NEW_CLIPPING define

- implemented RootLayer::SetActive(WinBorder*).
- added support for BWindow::Activate(). I realize now that I only added support for Activate(true). :-D In the next days I will add support for Activate(false).
- removed a few cases from ServerWindow as they are not needed.
- addapted WinBorder::MouseDown() to work with the new RootLayer::SetActive() implementation.
