Ogre 1.9 compatibility changes
Avoid killing AIWander and AITravel when far away

This fixes the problem of certain NPCs not wandering because they
happened to spawn near a cell border away from the player, which
immediately "completed" the wander package.

AIWander can't cause NPCs to cross cell boundaries, so there's no risk
of them walking into an unloaded to. AITravel will now simply stop
moving, and resume later when the cell is loaded.
