JS BC

I'd like to organize BC a bit better going forward, it's always confusing to me where to add new BC material and it's a mishmash. May as well start with it in JS (seems to shave 20% off the time on my save).

Rather usefully this has also exposed two issues, as the JS is more verbal. I think they are original to master and not to my conversion, but I could be wrong. They are both labeled TODO in this mr for the moment.

const pornGenres = App.Porn.getAllGenres();
	pornGenres.foreach((genre) => {
		if (typeof V.pornStars[genre.fameVar] === "undefined") {
			V.pornStars[genre.fameVar] = {p1count: 0, p3ID: 0};
		}
	});

Originally I just ran forEach() on the function, but App.Porn.getAllGenres() does not seem to return an object so this doesn't work either way. It originally used range in SC:

<<for _genre range App.Porn.getAllGenres()>>
	<<if ndef $pornStars[_genre.fameVar]>>
		<<set $pornStars[_genre.fameVar] = { p1count: 0, p3ID: 0 }>>
	<</if>>
<</for>>

I think it was failing, but silently.

<<if $nurseryNannies > 0>>
	<<for _bci = 0; _bci < $cribs.length; _bci++>>
		<<run App.Update.Slave($cribs[_bci])>>
		<<set _nurseryChild = $cribs[_bci]>>
	<</for>>
<</if>>

I have no idea why a temp var is set here, it does nothing and nothing else in the code uses it that I can find.

edit: ahh no, forgot you can't use forEach on objects, only arrays. derp.
