Add .gitignore (#165)

* Create .gitignore

- Created `.gitignore` with a list of possibly problematic paths
  - Created this as I started using VSCode's internal debugger for the project for some troubleshooting which created a `.vscode` folder with some configuration files

* Slim Down .gitignore

- removed irrelevant entries from `.gitignore`
  - Kept Desktop.ini and .DS_Store though due to them causing problems quite often
