Add a watermark to cards

Basic implementation

• Add a textual setting, which is used as the watermark text

Stretch goals

• Add a custom display for CardItems that show 2 cards, one regular, and one Saga layout.
• Make the watermark movable via drag&drop during configuration. Sync movement between the two previews.
• Add an angle setting to rotate the watermark
• Add a color selector to set the watermark color and opacity. Maybe use a slider for the opacity, since the transparency option in the Qt color selector isn't great
• Maybe allow arbitrary pixmaps as watermarks?

Basic support in place. Some of the stretch goals aren't implemented.
