[Feature Request] Add support for displaying source-relevant grid view cover art, via DuplicateHider integration

[Darragen]

Feature Description

When switching between a game's sources via DuplicateHider, Stardust will show source-relevant metadata, background images and logos, but not grid view cover art. It would be great if support for covers could be added.

Working Example (Screenshot):

Using the DuplicateHider showcase theme (DU_Night), grid view will show the cover art for either 'Arkham City' or 'Arkham City - GOTY Edition' based on which source is selected.

Cheers!
