Display Travis output in PRs with dangerbot

I think we could set this up to output the new module benchmark output, maybe even the dataurl output of a sample image as passed through each module?

https://danger.systems/js/

We could hide longer output in a <details> element which would be collapsed but expandable:

<details>
<summary>Outputs</summary>
...outputs...
<p>Module name</p>
<img src="...dataurl..."/>
</details>

This would be pretty cool!

This'll be really cool! We might have to output the benchmarks into a file, too, to make this work, though.
