## About The Pull Request

<!-- Describe The Pull Request. Please be sure every change is
documented or this can delay review and even discourage maintainers from
merging your PR! -->

Original code and new alert icons by Rylie, a few bug fixes and
modifications by me, and PRed on behalf of her.

The sweating alert icons specifically are from Citadel Station

Adds comfortable temperature ranges for species. Instead of the temp
indicator only showing up when you hit dangerous temps and start taking
damage, it will now show up once you exceed your comfortable range.

Being in temperature damage is now indicated by a sweating/fan overheat
alert for organics and IPCs respectively in the case of overheating, or
shivering if you're too cold.

Comfortable temp ranges are provisional, and Im open to changing them.

## Why It's Good For The Game

<!-- Please add a short description of why you think these changes would
benefit the game. If you can't justify it in words, it might not be
worth adding. -->

Gives a bit more nuanced feedback on your temperature, and provides a
transition state between from "you're a bit warm" to "you are now dying
of heatstroke" instead of immediately going from fine to melting alive
with no HUD warning.
## Changelog

:cl: Rye-Rice, Gristlebee
add: Comfortable Temperature ranges
imageadd: Temperature HUD alerts
/:cl: 

<!-- Both :cl:'s are required for the changelog to work! You can put
your name to the right of the first :cl: if you want to overwrite your
GitHub username as author ingame. -->
<!-- You can use multiple of the same prefix (they're only used for the
icon ingame) and delete the unneeded ones. Despite some of the tags,
changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->
