Bugfixes.

* Add newly created chunks to nearby players and NPCs. This fixes the
slider/static path mob pop-in problem.
* Update a player's chunks when resurrecting. This fixes a mob desync
problem.
* Use a private instance for the Time Lab
* Spawn a slider for every stop
* Fix mobs in private lairs using the template chunk mobs's current
health for their max health
* Don't call into the JSON lib in the loop in aggroCheck(). This is an
optimization found after using gprof.
* Don't print NPC deletions to console. This stops the spam when a
private instance is deleted.
* Changed default view distance to half the length of a map tile, so
chunks are aligned to map tiles
* Update tdata reference
