as a member, when content has been added to a deliverable, I see previews on the deliverable view

by default, if content/blobs has/have been added to a deliverable item, I see all the blobs in a justified grid in the central frame of the deliverable. No items are selected and the right hand panel shows the information relevant to the deliverable item(s)

AC:

• the binaries for "killed" deliverable items are not displayed
• the other binaries are displayed in a justified grid
• binaries are ordered by modified date, the most recently modified are on the top
