lib/bro: styling

[williamboman]

Not expecting this PR to be merged for multiple reasons.

I changed the output styling to something that I find much more readable. The way it parses the user-generated content is quite hacky, badly written and nonetheless unreliable, but 60% of the time it works every time.

Here's a preview image, thoughts?

And here's one with xargs;

Short explanation on how it parses submissions;

• It splits each submission string by \n.
• If the first line starts with a # it is considered a header (yellow, capitalized).
• Any subsequent line starting with # is considered a comment (green, indented).
• If the search query is found in a line, consider that line a shell command (prefix with $). Also highlight the match(es).
• If the line starts with a $, consider that line a shell command.
• Assume it's a comment otherwise.
