MANY improvements since yesterday!

Now, we can have EVERY kind of window properly displayed in the *right* order!
You can even use BWindow::AddToSubset and - it works!

Also Mouse click works to change front/focus state between windows.

Unfortunately window movement hasn''t yet been implemented and there are *minor* problems with the focus.
That's all! If you want to see something... construct a project and use:
* new BWindow()
*BWindow::Show()
*BWindow::AddToSubset[Of]()
and link against libopenbeos.so.

Ok now, bye!
