4527 - reading commandline arguments
The new example ex9 doesn't yet work natively. In the process I've emulated the kernel's role in providing args, implemented a couple of instructions acting on 8-bit operands (useful for ASCII string operations), and begun the start of the standard library (ascii_length is the same as strlen). At the level of SubX we're just only going to support ASCII.
