Added WISHBONE master bus submodule and some related top level signals but still
not much real functionality.
Added code to allow for memory access stalls.
Upgraded testbench to insert memory wait states. Added more error detection
and summery.
Improved instruction decoder. Still needs more work to remove redundant adders
to improve synthesis results.
