Pod Cloning changes

# Pod cloning changes
Pod cloning is broken right now (and also is horrifyingly slow), and this changes that.

### Changes:
>1. Sets the production on replica pods to 1 (from 10) by default.
>2. Replica pod cloning no longer is capable of producing anything but plantmen. SE's do not transfer to the new body, it is a "new" body.
>3. You can now replica pod clone someone without a body, if you have a sample of their blood before their body was destroyed.
>4. Blood will be considered unfit for use if it's been mixed between multiple samples, or taken from a suicide corpse.

### For fun, here's some other info:
>4 minutes 17 seconds - Cloning regularly
>1 minute 44 seconds - Speed cloning
>6 minutes 46 seconds - Production 10 replicant pod
>3 minutes 30 seconds - Production 1 replicant pod

This technically makes replica cloning better than regular cloning, but also steals away your humanity (And thus your AI protection), and speed cloning is still significantly superior to all options. In addition, you will still need someone to harvest your body, and the plant can die, so it's just a wacky alternative.

Fixes #6138 

Also, why do plantmen look stupid now, where are the old sprites
