Add preset for home page episode thumbnails (#954)

## Description
Adds a preset for "Episode thumbnails" which shows episodes using their
Primary image (ie a thumbnail or screenshot of the episode).

The previous "Thumbnails" preset is renamed "Series Thumbs" because it
uses the episode's Series Thumb image.

Also fixes a bug where toggling "Use series" might not update the home
page preview automatically.

### Related issues

### Testing
