This adds a system-wide default command queue. This queue is accessible via the new static system::default_queue() method. The default command queue is created for the default compute device in the default context and is analogous to the default stream in CUDA. This changes how algorithms operate when invoked without an explicit command queue. Previously, each algorithm had two overloads, the first expected a command queue to be explicitly passed and the second would create and use a temporary command queue. Now, all algorithms take a command queue argument which has a default value equal to system::default_queue(). This fixes a number of race-conditions and performance issues througout the library associated with create, using, and destroying many separate command queues.
