[Shadowysn]

Converted to new syntax and adjusted some things a bit. Haven't tested this yet, though.

EDIT: Silly me discarded the rest of the 'if's even though they already had a change - the distance. So I used an optimized function, and now all is good.
EDIT2: My habit of leaving in debug things has struck again. Commented them out.
EDIT3: This plugin previously didn't work because in the check-if-L4D1-Survivor function, it needed the player to be Bill and Zoey and Louis and Francis, not or.
Fixed it, sorry for having a brain fart.
