Changed X86CPU.reset() to not stop the CPU on a RESET (you can still force HALT after RESET by simply halting the machine manually before clicking RESET); moreover, by not calling stopCPU() in the X86CPU.reset() handler, we avoid problems in the CPU's speed recalculation logic (for example, if you repeatedly clicked RESET on a running machine, speed variables would get out of sync)

Changed the onclick handlers for Keyboard CLICKCODES to let updateFocus() scroll the canvas into view as needed, because (at least on iOS) the code that tries prevent the page from scrolling has an annoying "jerking" side-effect; also fixed the old Node web server code that would install onclick handlers for disk images, triggering automatic conversion of JSON to IMG files

Fixed an old annoying bug where a restored video card wouldn't properly display a blinking cursor; originally, I assumed it was a CRTC register restoration bug, but actually, some supporting variables (eg, cBlinks) were not getting initialized in both the reset() and restore() code paths. This is also a good time to remember that when an uninitialized array from some hardware state gets serialized and deserialized to/from JSON, the array is restored as a series of "null" values, not as "undefined" values, so it's best for any code checking for undefined values to use "== null" rather than "=== undefined".
