New Memory Layout

I have «invented» new memory layout for objects. Now creating new objects as well as wrapping simple data in object is very simple. The solution is to keep internal fields at negative offsets. The nm_object function returns pointer inside allocated block, and nm_release is able to find free and destroy methods out of this pointer. Additionally, deallocation of memory and destruction of object is now two different configurable operations. This allows me to create objects on stack or using ob-stacks or any other memory manager.

Working with objects is really simple now. I'm having fun with hacking nm again. :)
