Plasmaman speech no longer stutters the s's it's replacing.
Created by: Intigracy
Also removed it from happening on Unathi in case at some point they get added.
Closes #5111 (closed)
Before: "You're an asshole" = "You're an as-s-s-s-shole" (probably has more s's than this since stutter likes adding more letters) After: "You're an asshole" = "You're an ass-sshole"
