enforce that the address range of devices falls within the address range of the bus. Turned out that the CPU tests instantiate memory with the last parameter as memory size, not end address (fixed now). Also make sure that the address lookup array takes the offset caused by non-zero starting addresses into account.

rework bus. Don't throw an Exception any more with overlapping device addresses - this is normal for some machines. Introduce the concept of priorities to ensure that device overlap in the correct order.

Introduces several changes requested by Mario Keller. The simulator now has a variable step count that can be selected by a drop-down box on the main window. This change also displays ASCII characters in the Memory window.
