* Added two more private InterfaceDefs functions: get_application_order(), and

get_window_order() will retrieve the application respectively window order
  on the selected workspace.
* Moved private BeOS compatible functions (as used by the Deskbar) into the
  private WindowInfo.h header.
* Whitespace cleanup.
