Subject: ibuffer: add a new display option

* ibuffer.el (durand-reset-clearlist): Now an arg of '(64) triggers
  the display of the clear list in a temporary window showing all the
  buffers in the list along with their live status.  Maybe we can add
  more status to show in the future.  As a note, an arg of (list 64)
  usually means triggering the universal argument function thrice.
