Added a new work stealing queue

+ Added a new work stealing queue to Smart Thread, this one is much
simpler then the Link List one, but esencially it's just a fined grained
queue with 2 spin locks so it's much more stable in therms of perofmance
but slower.

~ I'm leaving both implementations and will later add code to change
them at will.
