Bug 13874: 'Rotating collections' are a circulation tool

Moves the entry for 'Rotating collections' from the Catalog
column to the 'Patrons and circulation' column.

To test:
- Verify the entry has been moved on the tools home page

NOTE: I agree that collections makes more sense under the new
      column.
