Need to put image upload on the /admin/items.html page

[evan-duncan]

This needs to be added to the /admin/items.html partial

<h3>Upload New Image</h3>
<input type="file" name="file" onchange="angular.element(this).scope().uploadFile(this.files)"/>
<div ng-bind="fileMessage">
</div>

It looks like the controller that uploads the images is shared by the /admin/items.html and /admin/item-details.html page, so this should be a pretty quick fix.

@eduncan26 - do we really need this on the items.html page. The controller should be ok if there are properties or methods on the scope that are not bound in the template. ???
