Adds missing runtime viewer Topic calls.

Relocates them to the datum itself rather than it being an admin topic for maximum self-containment.
Also adds 'adminplayerobservefollow', making it possible for admins to not only jump to mobs but also follow them with a single click.
Misc tweaks from Paradise.
