Ticket #2272: Block confirmation form should let enter trigger the 'yes' button

Setting focus into the form to make it easier to submit by keyboard. Enter or space will now trigger the button right off without having to mouse around to find the button after we've clicked into the conf form, and keyboarders can also get to the 'no' button more easily.
