Fixes: now setting correct frame time estimate, properly enabling the timestamp attribute, and ensuring that the Electron flushes screen work at least once per host frame update.

Certainly at least seriously considering a separate holder for the "compile a shader" logic. Otherwise taking steps back towards PAL/NTSC decoding.

You now get an Electron only if you ask for a new file. That'll do for now while it's the only thing that one might want to start without supplying a file. The 6502 now starts from a defined point — being reset. The Electron is starting to grow the absolute most simple buds of its memory map.
