Shelving Location Groups Interface Should Be Sortable

[Beth Willis]

The entries in the Shelving locations column sort alphabetically by System and then again by Branch.

The Group Entries column is not sorted alphabetically. This makes it difficult to identify which shelving locations from each System and Branch are included in the group, especially when displaying data at the Consortium level. I think the Group Entries column should sort alphabetically by default. I think it would also be preferable if both the Group Entries and Shelving Locations columns displayed locations owned by branches under the locations owned by their respective Systems.
