Bug 15321 - Add delete report link to Show, Edit and Run screens

Currently, if you are editing or viewing the results of running a
report and you decide you want to delete it, you have to go back
to the list of saved reports to do so. This patch adds a "Delete"
link in some convenient places.

To test:
- Apply the patch
- Make sure you have at least one saved report
- Make sure you have the create_reports permission
- Go to the Show, Edit and Run screens and verify the Delete link
  is present and functional, including the JavaScript confirmation
  dialogue
- Change to a user without the create_reports permission and check
  that the Delete link is not displayed on the Show, Edit and Run
  screens
- Sign ye off merrily!

Version 2: This version makes sure the JavaScript confirmation is
shown before an actual delete is carried out.
