Add "Cell -> Run All Keep Going" for notebooks

[cdeil]

I have this example notebook where I explain Python and IPython, and some of the examples demonstrate exceptions.

Now I have the problem that "Run All" stops on the first exception, but in this case I would like to going even if exceptions occur.

Would it be possible to add this possibility?

Here's an example demonstrating the current behaviour:

I'm not sure if this will do the trick... but how about:

Use IPython to present interactive demos¶
Use the IPython.lib.demo.Demo class to load any Python script as an interactive demo. With a minimal amount of simple markup, you can control the execution of the script, stopping as needed. See here for more.

and I didn't know about the nbviewer! Very cool that!

I'm not quite sure it is a good idea, nonetheless, you could wrap the example in try/except and display the traceback by yourself, eventually using IPython helper functions.

I think there might be a discussion about some kind of magic that does it on the list.

Otherwise you could listen to Js event to submit cell n+1 only when cell n is done.

I'll wait for other dev to give their thought, but I'm -1 on integrating it by default.
