Exposed member session data on site

refs https://github.com/TryGhost/members.js/issues/6

This exposes an endpoint on site url (`/members/ssr/member`) to get member's data in exchange for their session/identity on a theme when they are logged in. It essentially uses the same logic and data which is passed down to theme through handlebar helpers, and is used by members.js script to load member data.
