Lua API call to retrieve current store contents

Since we can send people to the store now through the Lua API, it would be nice to have access to the current store listings.

In cityscape type games, these listings could be used in place of advertisements in the game, whether would otherwise be a blank billboard, or a billboard with some fake advertisements.

I imagine the API would be a global function that returns the listings in a table, including the preview image, name of the item, and rarity.

  for _, v in ipairs(results) do 
    print(v.imageUrl,, v.rarity)
