stdout is not correctly rendered in some cases

[vanyle]

import pandas as pd

d = {'col1':[1,2],'col2':[3,4]}
df = pd.DataFrame(data=d)

df.describe()

On a jupyter notebook, the code above renders a pretty image:

This is not the case currently:

[vanyle]

kernel.py needs an update where the case 'text/html' in message['data']: is handled.

[vanyle]

By setting the gui property of the kernel_manager to qt, the output object type can look like parsed qt objects.

When the python is:

from ipywidgets import interact, interactive, fixed, interact_manual
import ipywidgets as widgets

def f(x):
    return x

interact(f, x=10)

Then, the message is:

{
   "data":{
      "state":{
         "_model_module":"@jupyter-widgets/base",
         "_model_module_version":"1.2.0",

         "max_height":"None",
         "max_width":"None",
         "min_height":"None",
         "min_width":"None",

         "object_position":"None",
         "order":"None",

         "padding":"None",
         "right":"None",
         "top":"None",

         "width":"None"
      },
      "buffer_paths":[

   "comm_id":"b4cd3d090bae463e95dcc46e1d23fdad",
   "target_name":"jupyter.widget",
   "target_module":"None"
}

In this case, it should be parsed to a Qt object and displayed.

Okay, I'll fix the pandas example. Treating outputs as qt objects should be an issue/enhancement on its own.
