Remove enqueue_1d_range_kernel() overload with no local work-size
Remove default local_work_size argument for enqueue_nd_range_kernel()
Remove explicit call to finish() in command_queue destructor

This removes the explicit call to finish() in the destructor
for the command_queue class.

The clFinish() function will be called automatically by the
clReleaseCommandQueue() function once the reference count for
the command queue drops to zero.
Remove read/write buffer convenience overloads in command_queue
Remove cl_int return values from command_queue

This updates the methods in command_queue to either return void
(for synchronous operations) or an event object (for asynchronous
operations). The caller will be notified of OpenCL errors via an
exception being thrown.
