Autobonus in combos and monster target drop

- Fixed Autobonus not working in combos (bugreport:8300)
  * Combos will now have a "pos" variable that saves the combination of equipment slots used
  * Autobonus now works with combined positions rather than just a single position
  * Autobonus should now also work with all equipment slots instead of just the first 15
  * This does NOT fix problems with multiple auto-bonuses activating at the same time
- Monsters will now stop instantly if their target is completely non-existent
  * This is mainly for looters that had their loot taken
  * Hide and most other situations still use the configuration setting monster_chase_refresh
