Rev 25360 Hotfix - CPU performance issue

General:

• Small animals have left Chernobyl. They will return when we rebuild their operation logic into something more efficient.
  
• We optimized the operation of portals used by monsters.
  
• We've optimized ranges from which specific sounds can be heard.
  
• We've changed the way the sound engine uses memory
  

All these changes should have a very positive impact on performance. Especially for people who have very good graphics cards and medium processors. Not all problems have been resolved, but we're working on it.

Thanks @Weston and @JafarElBaha. You were really a lot of support.
