Improving the Setup Experience

• Move "0 Setup" folder outside of genres folder and ensure it gets deleted if "Delete Setup Scene" option is enabled
• Assuming the setup folder was moved outside of the genres folder. The genres folder only contains well genres, and this means no more hardcoded folder names in setup script.
• Implement "Sub Genres". Each genre can contain multiple projects. An additional dropdown button should be added to the setup scene.
• Add option "Using VSCode?" If this is true then ask user for Godot exe path and modify the files in .vscode with it. Also set the new .csproj in .vscode files.
• Figure out how to queue the editor to close and re-open once all files are done moving around

Perhaps genres should be added as submodules so end user only chooses what modules they want to download.
