Delete button in Categories Manager fires Bulk Delete as well

If you select 2-3 categories, and then click DELETE on the line item of any Category listed, the javascript fires and deletes not only the item for which the Delete button belongs to, but all of the checked items as well.

If you have selected an item, and click delete on that same item, it tries to delete it twice, since the function passes the id from the button click, as well as the checkbox, so it has both, and gives you a strange error... like below.

Category 'xswxswwsx' removed
Invalid categoryID sent: 13, so skipped removal

The question is, do we want this behavior?
I believe its a bug.
Fixing 1 should fix both.
