This PR was made for staff discussion and should not be merged until staff agree on it.
Changed negative traits to no longer reduce the "traits left" count, allowing you to take as many as you would like. This allows people to potentially take up to five positive traits, provided that they take enough negative traits to gain the points.
Fixed non-custom species being able to completely ignore trait count and trait point limits.
Autohiss can now be set to Full/Basic/None from the character menu, and by default, it is assumed Full. It will respect save/load and client connect/disconnect, meaning you no longer have to constantly toggle autohiss.
Preferred Language can now be set. This allows a default spoken language other than Common to be set from spawn, allowing characters to simply join with the language they'd prefer speaking, rather than having to fiddle with "Set Default Language" every time they spawn.
Server rules do still apply, ofc. You must be able to speak Common or at least +understand+ it capably enough to do your job.

Yes, Autohiss is set underneath Egg Type. I wanted to use some of the space there. I can move it up under the Size/etc panels and speech verbs if requested.
Allows one to spawn with a backup implant. Rather than requiring it to be obtained literally every single time you spawn, you can just spawn with one instead, if you don't want to go to medical!
ICly there's no real reason why you would get your implant removed every shift, and OOCly if for some reason we decide to make resleeving not possible one shift, we're going to remove the resleevers, not the implants, so this should only really affect people who don't like getting implants every shift, and should make things a little less stressful for medical.
This function was WIP in the past on CHOMP.
I went ahead and finished this up, originally just for CHOMP, and then figured I'd backport it upstream.
TL;DR:
You can hit "Test Character Voice" in setup, to play a preview of what your voice will sound like with the selected type and frequency.

Both pre-made and custom species may now choose up to 10 messages each for warnings while overheated or cold.
If there are no custom messages, game falls back to defaults (which, if the pre-baked species lacks fluff, uses human)
There is a way to reset to defaults.
It is possible to go back and edit any of the 10 messages. The editor shows you the previously set message with an option to cancel out (this avoids over-writing the previous message).
