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.
• Figure out how to queue the editor to close and re-open once all files are done moving around

OS.Execute(OS.GetExecutablePath(), new string[] { "--editor" }, false);

This might work for restarting the Godot editor if its done on SceneTree.TreeExiting. Needs to be tested. I know GdUnit4 plugin did it so I know its possible.

Setup now restarts editor when done.

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