Fixed Auto-Traitor, Emotes for pAIs, Sprite Fix, Spider Nerf

- Removed Implanted personel from traitor list
- Added AFK check for traitors - replaces one traitor every roll if a
traitor has gone AFK
- Added temp debug messages in autotraitor to ensure above function
works as intended
- Added spawn limit on giant spiders. Once the limit(20) is reached,
spiderlings will be unable to spawn into giant spiders. When the total
number of alive giant spiders goes below the limit-2 (18), spiderlings
will be able to grow into giant spiders again.
- Added option for when an admin spawns spiders from the secrets menu to
disable the spawn limit on spiders. Option only appears if the limit has
not been bypassed yet.
- Added pAI's can now emote -Requested by Dalek-
- Fixed Advanced Energy Gun Sprite
