Replace emoji with jest-style colors

[lanwen]

I've experimented with some true-console experience
and tried to implement some jest-like badges.
That's not so distracting as more or less fits into
terminal color palette and resolution. I would say it
also feels a bit more like a professional tool, but that's for sure IMO only.

Just take a look and please tell me WDYT?

@lanwen thank you, the feedback is pretty positive so far. We'll give it a few more days to think it over. I'll give it a try too see how the interface behaves.

In the meantime if anyone has an opinion on this please speak :-)

FWIW, I quite like it!

@lanwen apologies for the delay on this,
I think we're close to merging, I decided to give it a go and it renders a bit differently to me:

Not sure why the OK, WARNING and FAIL render as grey. Seems to render differently for you. Could you look into making it black or something clearly visible before merge?

[sledigabel]

Perhaps a colors.Normal() is needed before printing the headers?

[lanwen]

sure, would try with a different color scheme in a terminal - seems it affects colors somehow

[lanwen]

@sledigabel pushed a change - seems that bold broke colors in some terminals:

when other looks fine:

not sure I can understand now why that happens :)

[sledigabel]

Tested, looks excellent;
Great work @lanwen, thank you for your contribution!

Great spot about the bold prints, I'm guessing the differences came from the terminal themes. Gruvbox seems to clear this out:

LGTM, modifies the logger look and removes the emojis.
