Breadcrumbs

## Breadcrumbs

* removed extra trailing slash from breadcrumb, this is being handled by the CSS
* empty breadcrumb for Home and Styleguide
* used ng-show instead of ng-hide on the breadcrumbs bar since it seemed like testing for presence would be more efficient than comparison.
* added repeater to iterate through breadcrumbs array and add a "current" class to the last item

## Feeds

* added a due date column to the feed index
