This PR makes the replicant outsider species a whitelist species after an application was made to play one as a crew member.
Added the Gamma Replicant station species, accessible via whitelist only. This species has additional weaknesses (radiation and shock). They have a few unique organs: The crew version of the rage heart can only activate once every 60 minutes (rather than every minute) but lasts for 40 seconds. The mending lungs repair a few organs very very slowly, instead of extremely quickly. The plasma sac generates plasma a little faster without added phoron.
Changed ventcrawl to specifically allow replicants to take underclothes and pocket sized items with them. I've balanced this for replicants only, but could remove the species check if wanted.
Changed alien and resin structures so that they can also be destroyed by replicants (though more slowly than aliens).
Added the user to the whitelist as approved here: https://forum.vore-station.net/viewtopic.php?f=45&t=2448&p=14179#p14179
Added a new whitelist species, the Hanner. These are the half-offspring of Lleill and share a small number of their abilities. Notably, they are shapeshifters, can drain energy from consenting people, can do basic alchemy and can transform into beasts.
Added the beast form ability to Lleill and Hanner, allowing them to turn into a small selection of simple mobs.
Changed lleill_energy and lleill_energy_max to be a base species variable rather than lleill species, allowing those abilities to be granted to other characters by GMs.
Added a small chance of finding potion materials in maint loot (pretty rare), to allow a little more consistent use of the alchemy ability for lleill, rather than relying on redgates alone.
