[nq] Reduce entity churn

Browse source 
While chasing down the grenade explosion bug, I noticed that entities
were being created and destroyed (or really, not destroyed) just to
check of the entity was valid. In the old system, this wasn't
*horrible*, but with the ECS, it does mean entities and components are
getting churned up, which wouldn't be good for the entity generation
counter (only 12 bits).
