0.7 python node: debug information is partial

[jbenoit44]

in 0.6.3, when something turns wrong in a python node, we get as a result a line number were the first issue is.
In 0.7, python node returns the failure, but user doesn't know where to check first.
also it is not shown in a watch node; only in information bubble.

Yes, definitely a big step backwards. The feedback we get from the Python ndoes now really isn't helpful at all. Please bring back the old behaviour.

Can we bubble the python trace back up to the iron python exception?

[Steell]

Yeah that's what was done in 0.6.3. We should be able to catch the IronPython exception and raise a new Exception with the Line and Column number added.

tracking internally as MAGN-3876
