Legion virus feedback (#3728)

## About The Pull Request

Makes the legion virus stage messages player-facing instead of
functionally nonexistent since my dumbass somehow didn't realize they
were tied to the stage increase probability. which is zero. yeah.
Also getting infected now shoves a message into chat which you will
probably miss anyways since it's surrounded by getting bitten and having
your bones melt. You WILL be able to tell if you have a new friend
though.

## Why It's Good For The Game

I thought people were dying because the messages weren't providing
enough feedback or something and it turns out they were providing a lot
more than not enough feedback since they were providing NONE!

## Changelog

:cl:
code: legion virus stage messages now properly display themselves.
instead of not doing that.
code: legion infesting people now give them a direct chat message. Say
hello to your new friend! They might be sticking around your body longer
than you will.
/: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. -->
