Cleaned up the handling of PS bits (not to be confused with PSW, which is PS combined with A); this fixes a bug where POP PSW was inadvertently disabling the internal interrupt flag (IF)

PC8080 bufferRotate option appears to be working as well the screenRotate option, so when everything else is working, we can choose whichever rotation method yields the best performance

...
It can be controlled with a new "smoothing" attribute on the <video> component and/or overridden with a "smoothing" URL parameter set to either "true" or "false"

The 8080 CPU goes through the Bus interfaces for all memory accesses now. The PCjs CPU maintained its own copy of Bus memory structures and interfaces, partly for improved performance but also because some CPUs can turn on address translation (ie, paging), making separate interfaces a necessity. However, PC8080 has much lower performance requirements and no address translation requirements, so we should revert to the original Bus interfaces.
