*   Added the following features to TensorFlow Debugger (tfdbg):
    *   Ability to inspect Python source file against TF ops and tensors
        (command `print_source` / `ps`)
    *   New navigation bar in Curses-based UI
    *   NodeStepper (command `invoke_stepper`) now uses intermediate tensor
        dumps. It also uses `TensorHandles` as direct feeds during successive
