Motivation:

To give a better first impression, and providing more comprehensive information for first time viewers, the README file needed reworking.

Modifications:

- Add a CHANGELOG file that at least redirects readers to the releases page of GitLab
- Update the CONTRIBUTORS list
- Change project README to have more information, flow better, and to have a better "first impression"

Result:

The README should give a stronger indication into the project's health.
