Makes it so having WALKMODE on doesn't crush people with the micro quirks (#4212)

## About The Pull Request

Having WALK MODE on makes it so you don't give micros any wounds/damage.
Knockdown still applies.
## Why It's Good For The Game
Giving people a way to not accidentally squish micros is good, having it
tied to walkmode which everyone can turn on willingly and not just a
quirk like before (Pacifism) is also good. The knockdown is still there.
## Proof Of Testing
