Starts to introduce a new grammar for ROM requests.
They can be optional, and chained together in AND or OR combinations. A central catalogue knows the definitions of all ROMs.

Switches the Electron to JustInTimeActor video.
Also reorders template parameters; I think that specifying a different time base is likely to be more common than using a divider.

The soft switch is LCBANK2, not LCBANK1.
[This also jimmys the IIgs into always entering its extended self test, for now]

For now, at least, c800–cfff is always built-in ROM.
Otherwise I probably need to extend my c3 logic to cover the other built-in cards (?)
