Add a confirmation dialog on article deletion
Add a confirmation dialog on article deletion

Problem: I have accidentally deleted a couple of articles because
"Delete" now has the same place as "Mark as read" before. The
potentially dangerous operation should have a confirmation dialog.

Solution: add a confirmation dialog on article deletion.
