make layout determined by actual size of the bubble and wrap lines

This is to better accommodate kernels like IRkernel which output rich text (e.g. HTML) for even small results.

Bubbles which only contain text (regardless of formatting) should have a multiline-result style bubble (pictured below) if they're larger than a single line, and should fit inline with no close button if they're small.

HTML results should also have the same close/new pane buttons as text ones if they only contain text.

@lgeiger Is this issue something you'd like to have a go?

HTML results should also have the same close/new pane buttons as text ones if they only contain text.

I can give it a shot.

This is the current behavior, isn't it?

[n-riesco]

Yes, it's the current behaviour.

I think the only thing that it's left to close this issue is to add the "copy to clipboard" and the "open in new pane" buttons in HTML result bubbles.

I'll soon make a PR!
