Bug 31204: Clearly indicate edit buttons are for record modification

To test:
1. Apply patch
2. Do a search and select some records
3. On the toolbar (#selection_ops) open the Edit dropdown.
4. The labels should read 'Batch edit records' and 'Batch delete records'.

Note: To see both you must have batchmod and batchdelete permission.
