preserve line endings in splitline ipynb...

preserve line endings in splitline ipynb Avoids discarding of information, e.g. `foo\rbar` should not be reconstructed as `foo\nbar`. Implemented in safe manner, where notebooks written by old scheme will load the same as before, and be updated on next save.
