Set the title labels to ellipsize at the end, fix the position of the
notification indicators, and hide the notification indicators when the item is
selected. We're hiding them because a later review request is going to allow
us to show additional widgets on hover and selection.
Testing Done:
Ran the turtles and opened a bunch of conversations and notifications. See the screen shots in the review.
