Added files:
        src/common     : APILinkedList.h AudioProcessingItem.h 

Log message:
        * Added class AudioProcessingItem, which will be inherited from classes 
that have anything to do with audio processing.
        * Added AudioProcessingItemLinkedList class, which is an extremely 
lightweight linked list, who adds/removes items without calling new()/delete() 
which is good for Real Time use
