* move gh-badges files out of /lib
As far as possible, this is just moving files
around and updating paths however there are 2
functional changes in this commit:
- remove use of lib/register-chai-plugins.spec
in badge-cli.spec.js
- remove use of starRating()
in text-measurer.spec.js
* update service tests that use colorscheme.json
* split package.json in two
* clean up import
* don't hard-code path
* start a changelog
* put a license file in the package dir
* re-organise documentation 📚
* don't pack test files
* remove favicon from Makefile
* give package its own test command
* link the docs better in README
