Update AttributeHelper.LoadAttributes so that InheritedGroupTypeId logic works in cases where the InheritedGroupType hasn't been saved to the database yet
Added constructor to RowEventArgs for cases where PostBack from grid is handled manually
CheckinConfiguration now handles when the InheritedGroupType is changed.  Also made it so that the CheckinLabels grid Add/Delete events can be handled (tricky since the grid is created dynamically inside the control, etc)
Merge branch 'origin/develop'
