Provide presets for QGradient

Similar to Qt::GlobalColor, the presets allow the user to create
brushes based on predefined gradients, quickly getting pretty pixels
on screen.

The presets are based on the linear gradients from WebGradients, a
free collection of gradients, hosted at https://webgradients.com/.
The few radial and blended gradient presets have been excluded.
