Implement ANSI colors in log view.

Maybe this'll help

• https://github.com/nteract/nteract/tree/master/packages/ansi-to-react

This isn't react-based, right.

Anyway, the biggest issues we have are these:

• one DOM element per-line
• line-oriented streaming
• So, colors may need to be remembered to be re-applied inside the next DOM element

Unless this is refactored to not do one DOM element per line.

The DOM elements per line are used for:

• Linking (through id)
• Making a visual marker per-line

Linking shouldn't be an issue to fix, add an empty <span id="L__" /> at the start of the line. It will make highlighting full line harder, but still possible.

Peppering more DOM elements to make visual delimitations between lines may fix the issue, or even a ::before for the empty span (which could also handle making the newline)
