Include gain controls for indvidual filters in Filter Wizard

[Ian Hudson]

I really like the flat wizard, it is one of the easiest and most intuitive of its type.

My problem is that I use 100 gain for broadband but higher gain for narrowband filters (imaging subs).  I would rather use the same gain (by filter) for image, flat and dark flat subs. But, if I use 100 for narrowband flats I am faced with 90s subs (plus 90s darks flats), that’s just too long.

It would be great if separate gain value could be defined for each filter type in the same way exposure is.

This is the same as issue I requested in #891. Linking here to include its votes.
