properties to a bunch of entity classes so they no longer need
a setup operation to get them going.

rulesets/Entity.h, server/WorldRouter.cpp:
Remove the setup operation sent to all entities on startup by

Make the tick property schedule the operation on apply(), and
use the property value as the time to schedule it.
* rulesets/InternalProperties.cpp, rulesets/InternalProperties.h,
server/CorePropertyManager.cpp: Add a pair of new property classes,
one to schedule an immediate setup operation, and one to schedule
an immediate tick operation.
