#124 SORROW DISPLAY - vids & sound thumbs

[Sibella Herbert]

Currently if a video or sound is affected by someone being sorrowed, it is still viewable to a user with administration rights, in lists with no warning that the media has a sorrow restriction on it, till the item is opened, then there is the warning in read text across the top of the page.

We need a sorrow thumb for video and sound, just as we have one for photos (the black thumb with "blocked for sorrow" typed across it).
