Spawned humans have DNA, strip panel is better

Fixes #4044
Fixes #4064

Spawned humans now have DNA, along with a randomized appearance and
name, making them similar to monkeys turned into humans.

Strip panel is now more organized and doesn't have any duplicated lines.
Won't work for humans spawned via the "spawn" verb. This code is also a workaround and doesn't fix the issue, especially if there is new code to create a human; these lines of code would have to be copied everywhere.
