Overwhelmingly wide plots

[RaphaelArkadyMeyerNYU]

Images output by cells seem to always use the entire width of the window. This means that, on a landscape screen, a square plot does not fit on my monitor. This makes working with plots utterly unreasonable.

As an relatively quick fix, I suggest that we should be able to specify either

• A fraction output_image_relative_width (default value: 0.33) in the settings such that the output images have width = output_image_relative_width * window_width OR
• A fraction output_image_width (default value: 500) in the settings such that the output images have width = output_image_width

I work in Julia, which produced the following output with the pyplot library that appeals to matplotlib:

(If I change the size=(1000,1000) to take different values, this changes only the resolution of the plot generate. It does not change the actual size of the image drawn)

Turns out this is just the same as #108
