Add "Product Image" column in Inventory Search

It'd be awesome to see a small graphic of the parts in the Search Inventory list view.

I'm not sure how hard this would be—since it takes a while for product images to load whenever I click on a specific part seems like they might currently be cached/downloaded in the database, but I presume that'd be required to make a list view work at a reasonable speed.
