 Customize: Re-architect and harden panel/section UI logic.

 Removes contents for sections and panels from being logically nested (in
 the DOM) in order to eliminate many issues related to using `margin-top`
 hacks. The element containing the link to expand the content element for
 panels and sections is now a sibling element to its content element: the
 content is removed from being nested at initialization. The content
 element is now available in a `contentContainer` property whereas the head
 element (containing the link to open the construct) is in a
 `headContainer` property. The existing `container` property is now a
 jQuery collection that contains both of these elements. Since the head
 element is no longer in an ancestor element to the `content` element, the
 `aria-owns` property is now used to maintain the relationship between the
 `headContainer` and the `contentContainer`. These changes are also
 accompanied by an improvement to the animation performance for the sliding
 panes.
