Payload missing should be handled

[Carreau]

See JuliaLang/IJulia.jl#325 (comment) where ipython console --kernel julia crashes

cf jupyter/qtconsole#21 also

Note that I was using IPython 3.0.0, so it would be good to check whether this has already been fixed.

[Carreau]

Well you should at least update to 3.2 that fix some XSS vulnerability on notebook...

[stevengj]

Okay, looks like Anaconda has 3.2, so I will try updating...

Got the same error in IPython 3.2.0:

  File "/Users/stevenj/anaconda/lib/python2.7/site-packages/IPython/terminal/console/interactiveshell.py", line 208, in handle_execute_reply
    for item in content["payload"]:
KeyError: 'payload'

Looks like the unqualified check for a payload is still in git master.

Fixed by #10
