In preparation to work on #10163, I've spent some time adding a feature I've wanted to add for quite some time now for Faiths, and gathering notes on the current MobV2 dev experience and what is needed to improve the experience. This PR goes over a lot of changes, so I'll highlight some things about the two major additions in this PR before the changelogs.

Hellspawns join Nanotrasen's workforce.

Due to several incidents involving plasma and fire-hazards onboard Nanotrasen's stations, central command has deduced that it is cheaper to hire fireproof crew-members instead of re-introducing OSHA regulations back into space. After some corporate espionage, and several blood sacrifices from a curtain pact of blood brothers; Tieflings have been summoned into Unitystation's newest roster of playable species.

A beautiful Humanoid

Tieflings are androgynous creatures, who are closer to humans and felines in features. What makes them stand out more is their exotic skin colors, slim legs and tails, and their ability to grow horns!

Humanoids from hell

Tieflings are Hellspawns, their natural climate is usually even hotter than Lavaland's atmosphere. As a result, the station's natural temperature might be a bit chilly for them. We recommend providing jackets, explorer suits and winter clothing to your hellish friends to keep them warm.

Natural Firefighters

Being a native in hell has its positives. Tieflings are naturally more resistant to fires than any other species (even lizards!).

Do be aware that they're only fireproof, inhaling plasma is still toxic to 90% of all recorded species!

A True cat

Tieflings have night vision, which allows them to see not one, not two, but three whole tiles ahead of them in the dark!

Burning hooves

Tieflings have legs and hooves that are hotter than the average humanoid leg, which disallows them to wear any kind of clothing on their feet, as it not only uncomfortable for them; it can also result in many burnt shoes and socks.

The Ashwalker forces strengthen..

Due to Nanotrasen's and the Syndicate's meddling with forces that are beyond their own comprehension, some forces from hell have taken interest in the sudden migration of Hellspawns into the mortal realm; and have revitalized a threat once thought to be pacified by central command.

The nest hungers, and a new ally from the depths has come to feed it.

The Ashwalker Priest

For a couple of years now, Ashwalkers have had a major flaw that made their whole gimmick pointless, which pacified them and made a lot of people stop looking at Ashwalkers as a likely antagonist; Ashwalkers did not have the means to feed the nest, which nullified the whole point of its existence. Until Today...

The Ashwalker Priest is a support ghost role that is designed to help Ashwalkers fulfil their goal using their magical abilities.

Priests can heal other ashwalkers, and harvest meat/skin from killed creatures.
