Add a "delete" button in view and edit actions

Add a "delete" button in view and edit screen (on the side of "edit" button on right top of view screen).

Hey, thanks for the idea!

I guess, we can link this to #872. If we give the option to show certain item actions on the show view, that would also allow you to display the delete action.
