Rev 25360 Hotfix v2 - Major FPS boost

• We have finally been able to solve the problem that caused huge drops in fps for some players. Now your fps in the game should coincide with those in the benchmark.
  
• Optimizations in our main Hero class should improve even more the game performance for people with a weaker CPU.
  
• Optimizations in the sound system should improve the overall performance of the game.
  

Once again thanks to @Weston and @JafarElBaha, who helped us detect and solve the problem. Let us know if your optimization problems have also been resolved and if the game is already running smoothly.
