The CONTRIBUTING.md file can be in the root directory or
in the .github directory and will still be used for
the contributing guidelines on Github.
Moved back to the root directory so that it is more
visible outside Github
This commits adds an issue template for contributors that open bug
reports or feature requests.
Additionally, this commit adds a .github subdirectory to the project and
moves the CONTRIBUTING.md file to that directory.
