Reverted previous update.

Now verifies body type after the pawn is generated.

Removed unnecessary assembly files.

Now compatible with v1.6.

Fixed an error related to `PawnGenerator.DiscardGeneratedPawn`.

* Now prevents some errors when the pawn's gender was changed, which prevented them from spawning. Enabled by default; can be disabled.
* Now uses `PawnGenerationRequest.FixedGender` instead of manually modifying it.

* Added `Set Fixed Gender` (enabled by default; can be disabled,) which is for compatibility with other mods that also changes the pawns' gender.

* Now has a hard limit on how many times a pawn's gender is re-rolled.
