This patch adds a JavaScript confirm to the deletion of files. It also
styles the file deletion link as a Bootstrap button.
To test, apply the patch and open the "Files" page for a patron who has
files attached.
- Verify that clicking any "delete" link prompts for a confirmation.
- Verify that confirming the dialog triggers the deletion of the correct
file.
- Verify that canceling the confirmation dialog aborts the deletion.
- Confirm that the "Delete" button looks correct.
