Ability to turn on/off Group Submission feature (assignment.group.submission.enabled=true must be set in sakai.properties)
This patch makes changes allowing Site Groups to act as submitters of an Assignment instead of an individual. Any individual in the group may make submissions/changes and all members of the group are emailed notifications on submissions. All behaviors on individual submissions can be applied to Group Submissions such as Grading, Resubmissions, Grade Release, Downloads, Uploads, etc. One grade is designated for the entire Group and all individuals receive this grade in the Gradebook (A future patch is expected to include a mechanism to alter an Individual's grade from the Group's grade).
Ability to turn on/off Visible Date feature (assignment.visible.date.enabled=true must be set in sakai.properties)
This patch also includes an optional visible date feature. If visible date set, student can see assignment but can not submit/save yet. This feature is driven by a need for us to show students upcoming tasks but not allow them to act on them until the open date.
