 Bug 13132: Add confirm dialog for deleting reports from the reports toolbar

To test:

1) Go to Reports -> Use saved (or build a new one if you have none saved)
2) Click on the Actions drop down and confirm that when you click Delete from here, a confirm message shows up. Click Cancel.
3) Click Show in the drop down menu
4) Click Delete in the Reports toolbar. Confirm you now get a confirm message. Clicking Cancel will cancel the delete, and clicking OK deletes the report and takes you to the saved reports page.

After applying the patch I get a JavaScript popup confirmation when
I click on the delete button, in the Show, Edit and Run views. Nice!
