Title: Added configurable template for the short-object-description

This way the template can be overridden per entity or globally and we can choose how to represent the entity for the admin bundle without stuffing logic in the entity itself.

One practical example is that you can show a clickable thumbnail instead of just text.
Like-wise galleries of the media bundle can choose to directly show a thumbnail for the media file instead of just the filename.
