Add media browser to multis

[marktaipan-cvisionai]

Category Feature Request

Problem Currently users cannot access a single media's attribute list while in annotation-multi. They have to open another page and open the specific video in a separate annotator.

Request Either add a "go to" link for each of the single videos in the multi or extend the existing entity-browser to cycle through the media like other entities. There would need to be a visual indicator denoting which media is selected.
