Set-up and link to available browse pages

[artlowel]

Use the new BrowseService methods created in #255 to configure the available browse pages in the UI.

a browse page should be available for each browse index available on the REST API

For the entire repository, the routes should be /browse/:index-name for the entire repository, so e.g. /browse/author

For a collection or community the route should be /collection/:id/browse/:index-name or /community/:id/browse/:index-name, so e.g.
/community/9abbd9e5-51d9-45c5-a2ec-dae4c8cfc280/browse/title

Create a component that renders the available browse options as a set of nav-pills, similar to the way it currently looks in xmlui. It's probably best to use the flex layout in order to stack them vertically on xs screens, and horizontally everywhere else.

The component should have an optional scope @Input. If it's left out, it should link to the entire repo's browse pages, if it's there it should limit the pages to that scope.

Put it on the homepage, and on community and collection homepages.

This has been mostly taken care of by #421

The only thing that's missing are the links on the collection and community homepages, that will be part of #472

@artlowel : I believe this ticket is now resolved? Could you verify?

You're right.
