Implement UI for entry re-order when chronological order changes.
=================================================================

The UI should re-order the EntryList display when the chronological of the entries
changes based on user input.

Two ways to do this spring to mind:

1. ``slideUp`` the EntryView at it's original position, find the new position,
   move it in the DOM and ``slideDown`` the element into view.
2. Detach the element from the list, position it absolutely, animate it to it's new
   absolute position (based on the position of its new neighbors) and re-insert it
   into the list.
