* fix 'cannot scream while unconscious' bug
fixes a bug where it tells you that you can't scream while unconscious while on fire (experienced on Bagil when a plasma fire happened at endround shuttle)
* Update species.dm
* sanitize code
* add the comment back so people know what it doin
* change operator
other one wouldn't work with the fix, the screaming is supposed to happen while you're in crit
