GetFloorAndItemTriggers() was removed in favor of TestTriggersAtXYZ() from switch.cpp, which does the same. All calls to GetFloorAndItemTriggers were replaced with TestTriggersAtXYZ. Pushables pulling bug was fixed in TestBlockPull(). PushableBlockControl() now calls ItemNewRoom() to signal change of room membership of pushable.
