* Sideports a couple of init unit tests from Neb.
* Trying to unfuck initialize logic.
* Removing del()s.
* Adjusting return values to Initialize().
* Moving some dangerous object logic from obj onto the two types that use it.
* Rolling back some init changes and commenting out initialized atom unit test.
* this comment formatting is a minor war crime
* Removed sleep() from signaler circuit Initialize().
* Additional Init fixes post-rebase.
* Uncomments subsystem test since that's passing.
* Adds defines for world.tick_usage
* This provides no useful benefit whatsoever, but /tg and Baystation12 have done it, so it will make porting future code easier if we do too. No real harm done either.
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.
