Woe, mpreg curse upon thee

About The Pull Request

Adds the forbidden Baothan mpreg ritual. Shamelessly copied code from Azure-Peak#4659 that I can only guess won't break anything, but it seems to compile and the ritual appears to work, though I can't exactly test that it ACTUALLY 'works'

Developer's checklist

• I have modularized whatever changes I could. (I did copy and paste code, so I don't really have a great understanding of how it works,
• I have marked the start and end of my edits outside the caustic modular folder (if applicable) for changes that I couldn't modularize.
• It compiled locally, and I tested new features, or potential issues with related features, to the best of my abilities.
• This change applies mainly to our server, and wouldn't be in a better place upstream / cannot wait until the weekly upstream update.

Testing Evidence

Couldn't test whether the actual 'mpreg' part works, but you can select the ritual and cast it on yourself as a Boathan, and a womb tattoo marking appears, so there's that.

Why It's Good For The Game

Well, that's a bit subjective, considering this is just fetish content, but I guess appealing to a specific fetish isn't necessarily a bad thing.

Changelog

Changed Boatha's rituals so now its not just a ritual of joy, but also an mpreg ritual.

If only I wasn't critically stupid in how to work Github and know how to resolve conflicts when the 'Resolve conflicts' button is greyed out.
