Added created and last modified timestamps to the group_app model.
Also edited the templates to show some extra information. The review template has the names for the new properties hard coded because the auto_add and auto_add_now datetimeproperties don't show up in the fields of the entity.

hashlib module containing both hash algorithms. Here, we provide a common
interface to the md5 and sha constructors, preferring the hashlib module when
available.
