Include additional media types in Last Chance Cadet and Matching widgets

[wilmahodges]

In the Last Chance Cadet and Matching widgets, it is currently possible to include audio media files. However, image files and video are not available. We have had requests from users who would like to be able to add images associated with matching set items for both of those activities. It would be nice to support the option for video media as well, although that media type wasn't specifically requested.

Thanks for the suggestions 👍 this isn't the first time we've seen requests for additional media types for Matching and LCC. I'm moving this issue to the Matching repository since the code changes are scoped to the individual widgets, not Materia.
