[Sugar-devel] [RFC PATCH 6/8] Add sort_by method to the journal list view.

[Andrés Ambrois]

This method triggers the actual sorting. This is done by placing a 'order_by'
value in the query, and calling the datastore to retrieve the sorted data set.
The sort_column is also modified to display the property we are sorting by.
