Fix the change description boxes to allow collapsing/expanding.
Review Request #4200 — Created June 3, 2013 and submitted
Fix the change description boxes to allow collapsing/expanding. Review boxes were made collapsable/expandable, but this didn't end up applying to change description boxes. Now there's a base view called CollapsableBoxView that handles everything having to do with collapse state. ReviewBox inherits from this. ReviewBoxListView sets up a CollapsableBoxView for every change box on the page.
Tested expanding/collapsing individual review boxes, change description boxes, and all at once.
