Rework logging colors (MagicMirrorOrg#3350)

- Replacing old package `colors` by drop-in replacement `ansis`
- Rework `console-stamp` config to show all Log outputs in same color
(errors = red, warnings = yellow, debug = blue background (only for the
label), info = blue)
- This also fixes `npm run config:check` (broken since
6097547)

Feel free to let me know if the PR is too big and you want me to do
individual PRs for the changes.
