LibCards: Make the card back image configurable

Browse source 
`CardPainter::set_background_image_path()` immediately repaints the card
back and inverted card back bitmaps if they exist, so users just need
to `update()` that part of the screen. This is handled automatically by
`CardGame`, but other users will have to do this manually.
