The logranger.toml file is moved to the 'etc' directory, and its pid_file location is updated. The .gitignore file is also edited to ignore local configuration files in the 'etc' directory to prevent them from being tracked. This creates a cleaner project structure and ensures local configurations are kept private.
All source code files as well as README.md, .gitignore, and various configuration files have been updated with an SPDX license identifier, changing license from CC0-1.0 to MIT. The copyright year has been updated to 2023, and the copyright holder's email address has been corrected from 'winni@neessen.dev' to 'wn@neessen.dev'. An MIT license text file has been additionally added.
This commit introduces a SonarQube configuration setup, adds an .idea/.gitignore file, and expands the root .gitignore file. The SonarQube setup includes a GitHub Actions workflow and a project properties file. The .gitignore files are updated to properly ignore files for JetBrains IDEs, local testfiles, SonarQube, and others.
