Fix crash involving polygon being too empty

GCC doesn't like me using QStringLiteral here

Use Mapbox's ear clipping algorithm to handle drawing any simple polygon

Edit tools: get rid of the preview polygon and render the result-to-be

simplify settings further

Further reduce settings.h

fix comment

Replace config collector with a simpler system
