Remove AnnotationUIController

All of the functionality in this module is either unused or duplicated
elsewhere:

 * The $scope.{selectedAnnotations, focusedAnnotations,
   selectedAnnotationsCount} properties were unused.

   Note that there is a very similarly named `selectedAnnotationCount`
   scope property defined in `WidgetController` which _is_ used

 * The ANNOTATION_DELETED event handler duplicated another one in
   root-thread.js
