Subject: [PATCH] Bug 16949: Batch record deletion says success when no records
 have been passed in

The reason this happens is because the page will say success when the total number of records given equals the total number of successful deletions. If you pass in no records, there are no successful deletions --> 0 = 0 --> it thinks it has been successful. This patch adds a check that validates if any checkboxes were selected before submitting the final form.
I have removed the check for if any records were selected AFTER the form
has been submitted because it seemed unnecessary if the form can't be
submitted without selection of records anyway.

To test:
1) Go to Tools -> Batch record deletion
2) Put in a record number and click Continue
3) Deselect the record so that it doesn't actually delete and click Delete selected records
4) Page says 'All records have been deleted successfully!'
5) Apply patch. Go back and repeat step 3
6) Form should not submit and you should receive an alert saying that no records have been selected.
