setup is literally a copy of misc.

VSCode and typescript still do not understand assignments to window as
introducing of a global name. To make them happy, use assignment to
globalThis.

Add setMissingParents function which makes sure slaves have parent IDs set before generating clones/siblings/etc.

2. When normalizing empty wombs, reset pregSource even if it's negative
3. Add TerminatePregnancy utility function to terminate a pregnancy with the appropriate postpartum length
4. Rework a whole bunch of places where pregnancy is terminated to use the appropriate functions and not set pregType/pregWeek/etc directly
5. Add postpartum delay when pregnancy is completely terminated by individually removing the last ovum from pregnancy inspection

Fully renormalize pregnancies after removing a fetus.  Avoids some bad states when ovum 0 is terminated, especially if it's the last ovum remaining.
