zatackax: init at 1.1.0

Zatackax is an open-source remake of the early computer game *Achtung,
die Kurve!*  More information can be found on the projects
[GitHub](https://github.com/simenheg/zatackax).

Packaging considerations:
- **Is the package ready for general use?**
  Zatackax was originally released in 2010, and is still passively
  maintained to this day.
- **Does the project have a clear license statement?**
  Zatackax is licensed under GPL3+, as declared in its README.
- **How realistic is it that it will be used by other people?**
  Zatackax is currently packaged by Debian, OpenSUSE, the AUR, and more.
  A full list of repositories which include Zatackax is included on
  their README.
- **Is the software actively maintained upstream?**
  Zatackax currently recieves passive maintenance.  However,  it is not
  a security-critical package, nor is it integrated into a fast-changing
  ecosystem.
- **Are you willing to maintain the package?**
  Yes.  While I did choose to contribute this package first as an
  exercise to help familiarize myself with the process of contributing
  to nixpkgs, and I forsee only a very small maintance burden from this
  package, I understand that I am taking on a multi-year commitment, and
  am willing to provide maintainership for at least a release cycle, and
  likely much longer.
