- Added read and write barriers to the actor pointer in the sound channel

structure.
- Fixed: Items which should stay but had an IF_ALWAYSPICKUP flag were removed.
- Fixed: The pickup flash must only play when an item is picked up so the 
  correct place to spawn it is in AInventory::Touch, not in AInventory::GoAway.
