This PR adds the following sounds;
Death sounds
Scream sounds
Pain sounds
Gasp sounds
The sounds are organized into a category under character setup - navigate to the VORE tab and select one based on your preference. If Unset, or not chosen, it will default to whatever the icon base is for your species - for instance, Vulpkanin will get the Canine sounds.
Sounds are grouped into 4 major lists so far, with plans for more once I get more files;
Canine (Scream/Gasp/Death/Pain)
Feline (Scream/Gasp/Death/Pain)
Cervine (Scream/Death only)
Generic/Human (Scream/Gasp/Death/Pain)
Vulpkanin use Canine sounds. Tajaran use Feline. Humans get Generic/Human. Cervine is unset on any species, allowed to be taken by customs.
Vox have a pain sound.
This also enables **pain** emotes. These can be manually done with *pain, or triggered automatically on taking an injury. The pain trigger respects species pain mods - for instance, if you have Major Pain Tolerance, you'll hear yourself growl in pain far less than someone who has Intolerance.
Pain is **not** triggered by spicy food or hallucinations, as those two add halloss on directly. Only effects that apply damage will add on pain.
You can test out these sounds in the Character Setup panel. See [here](https://streamable.com/o9wr9g), and here:
A demonstration of human sounds is available [here](https://streamable.com/hqwpel).
Canine sounds [here](https://streamable.com/41d0oj)
Demonstrations of it during combat [here](https://streamable.com/y4nxea) and [here](https://streamable.com/gj2gl3).
These can be muted by navigating to Sound and setting the Mob Injury Sounds variable, seen here:
Species that currently lack sounds have had their audible sounds disabled to prevent jarring human noises from playing on non-human species. This can be overridden upon request, but for now, it will serve as hopeful inspiration to encourage additional files.
Preferences can now take a list instead of a singular datum (but will still accept a singular datum for legacy compat), and any arguments that check is_preference_enabled must return true on all prefs from the list, not just one.
