* Forgot to update Screen.h with the last commit...

* Introduced and implemented AS_GET_SCREEN_ID_FROM_WINDOW - it only returns B_MAIN_SCREEN_ID,
  though.
* renamed ServerWindow::fHandlerToken to fClientToken.
* The BScreen(BWindow *) constructor now really asks the server for the screen ID.
* ServerApp::fWindowList is now a BObjectList.
