LRS-34 Statement Rendering/Browsing

[milt]

LRS-34 /statements UI/browser interface

This PR adds the ability for the LRS to render the GET method of the /statements route as html if provided with the Accept: text/html header.

The functionality can be toggled with the :com.yetanalytics.lrs.pedestal.interceptor/enable-statement-html key in the service map.

If authentication is implemented and html rendering is enabled, :com.yetanalytics.lrs.pedestal.interceptor/www-auth-realm will specify the basic auth realm for browser auth. Users will get a login/pass browser dialog and then be able to browse.

By default the server will render full html pages, but fragments can be requested with the unwrap_html=true query param.
