Scaling plot size to the browser size for bulk text

[anastazie]

I noticed that in order to make adjustable sizing, sizing_mode="scale_both" need to be added also to rows and columns layout, e.g.

controls = column(p, text_filename, save_btn, sizing_mode="scale_both")
return doc.add_root(row(controls, data_table, sizing_mode="scale_both"))

If you could make a screenshot of the before and after I will gladly consider it.

That said, I feel the future of this library is to move away from Bokeh and move everything to the Jupyter notebook with widgets instead. I don't mind keeping the current app around but I am not planning on giving it priority in favour of the other new features.
