Drawer closer and expanders rendering in the wrong places.

[blazebarsamian]

Background: The drawer expander and closer positions need to be swapped. rev-Drawer-expander should be inside rev-Drawer-contents. and rev-Drawer-closer should be outside (above) rev-Drawer-contents

When I use:

<%= drawer closer: "-", expander: "+" do %>
   drawer stuff
<% end %>

It renders out like this:

<div class="rev-Drawer">
  <a class="rev-Drawer-expander" data-rev-add-class="rev-Drawer--open" data-rev-init="true" data-rev-parent="rev-Drawer">+</a>
  <div class="rev-Drawer-contents">
    <a class="rev-Drawer-closer" data-rev-init="true" data-rev-parent="rev-Drawer" data-rev-remove-class="rev-Drawer--open">-</a>
      drawer stuff
  </div>
</div>

But it should render out like this:

<div class="rev-Drawer">
  <a class="rev-Drawer-closer" data-rev-init="true" data-rev-parent="rev-Drawer" data-rev-remove-class="rev-Drawer--open">-</a>
  <div class="rev-Drawer-contents">
    <a class="rev-Drawer-expander" data-rev-add-class="rev-Drawer--open" data-rev-init="true" data-rev-parent="rev-Drawer">+</a>
      drawer stuff
  </div>
</div>
