This commit will add the campus logic to the ead2_config and also change
the rake's reference to the app's version.

This commit will add relevant SVG files for the breadcrumbs and a few
helpers as well as some SolrDocument methods that we'll need.  The main
thing is adding the Ngao::Arclight::BreadcrumbsHierarchyComponent
because we want to override the breadcrumbs_hierarchy_component view.
Overriding view component views are a little different that regular view
files where if you match the path you'll be set.  This required us to
create the component object in this application and then it would be
able to pick up the overridden view component erb.

This is just for the convenience of uncommenting and restarting instead
of needing to type it in every time.

This will render the campus in the facets field.  All of the changes
came from the current ngao app.

This commit will add the campuses to the index page and do some minimum
styling.  Also the scroll to top button was added as well all its
accompanying files.  The repositories.yml was updated to NGAO's current
one so we can see more than one campus.  We also introduced a decorator
pattern to override the repositories controller to add the campus logic.
