Title: Do not hide the exception details while there is no way to show them.

I familiarised myself with the code of sagenb enough to know that you are using a completely different javascript framework for generating the user interface; and one in which cycling through the ncols options (as was done in the older sagenb) is not really relevant. As such, it did not make sense to reimplement this code; and so I have just commented out the code which hides the traceback information. For obvious reasons, traceback information is important to show in the worksheet.
