Revamp Custom Settings for better clarity

[dragon3025]

I'm getting the impression that the "Difficulty" setting in Custom Mode applies invisible changes which gets multiplied to the sliders below it, but if you go to Whoa Mode the sliders below change, so I'm maybe it doesn't? I think it would be great if the "Difficulty" setting in custom doesn't make invisible changes, but instead sets the changes to the sliders below it with added sliders for Whoa Mode changes like Food Spoilage timer rate, Sizzle Meter Fill rate, added creatures (for example: 2 Widows in the Den), etc. Also, a way for more accurate increments.
