Subject: [PATCH] Fixed: Possible invalid processing for Crash states that
 immediately destroy the actor

- Setting an actor's Crash state has the potential to destroy the actor if
  the Crash state has one or more 0-tic states that end with Stop. This
  was not taken into account when the object's Z velocity was 0, but it
  was under the floor anyway.
