dmaHD sound engine

Hi Barbatos,

This is all original code done by me in October 2010 released November 2010 and used in UrbanTerror 4.1 since then, it is approved by leagues since it does not remove or add sounds and is faithful to the original listening distances of the original sound engine. It is much more optimized than iKalizer and thus gives more FPS. More information can be found at the UrbanTerror forums link below:
