Add a "Delete Voicemail Confirmation" Dialog Box to ARI

My customers will sometimes tell me that in ARI they inadvertently deleted a voicemail, that they really wanted to move to a folder.

Ideally there is a standard, "Do you really want to delete these files?" confirmation box that is presented prior to the deletion of the voicemails.

Since you can't do dialog boxes in PHP, this would have to be added through some client-side Javascript.
