Projectiles are no longer bloodthirsty for stam/softcrit people (#3177)

<!-- You can view Contributing.MD for a detailed description of the pull

## About The Pull Request

replaces stat == dead check with a generic stat check because any stat
above 0 means the target is incapable of doing much of anything

Stamcrit now gives TRAIT_HANDS_BLOCKED like other stuns, this shouldn't
do much except allow projectiles to fly over them since you can't do
hands stuff in stamcrit anyway

## Why It's Good For The Game

I don't WANT to fill the poor sod in the front with 500000 rubber
bullets I WANT to crowd control!!

## Changelog

:cl:
code: People who are stunned are now more reliably passed by bullets not
aimed directly at them
/: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. -->
