Implement exposure equations and matching for Aperture menu

Also: More evidence I am in a continual half-daze

- Need to define shutter value as double in `aperture` as otherwise both
arguments will be integers and I'm guessing it'd not going to work out
well. Plus... need to use `fraction_to_double` anyway to feed the
value in.
- Had done the "substring" thing wrong in `strncpy` and was one decimal
place off in getting the paerture value. I.e. would have got "1."
instead of "1.4" from "f/1.4"
- Like the fool I am, in the loop and the copy and paste I'd done, I'd
not changed from `aperture_array[0]` to `aperture_array[n]` check-in: 845d8653eb user: base@atomicules.co.uk tags: origin/master, trunk
