resize ipython notebook output window

Addendum #2: This comment: https://github.com/ipython/ipython/issues/2172#issuecomment-53708976 indicates how you can increase the maximum size of the output cells. Run the following code in the notebook:

%%javascript
IPython.OutputArea.auto_scroll_threshold = 9999;

You can toggle the scroll window in the main menu of the notebook

Cell -> Current Outputs -> Toggle Scrolling
