VID-1955 Add widget for Crunchyroll in lightbox + file page & add inline option for media

This might be more of a personal preference than a necessity, but I'd like to wrap all crunchy roll players inside ```div.crunchyroll-container``` for consistency. That way if a developer sees one crunchy roll player with the wrapper and uses it to style/select something, they can safely assume that all crunchy roll players have that wrapper.
