Remove/replace/rebalance rarely used traitor items

[Bartimeus]

As flaborized said, there's a need to figure out if an item is not purchased because its bad, because its unfun, or because the other options in it's category are just outclassing it by alot. For instance, you rarely see mustache grenades used, or the syndicate pipebomb, or even the bowling kit, but people often do gimmicks around them that makes the round a lot more fun. If an item is objectively terrible, sure, it could use a buff. But not all traitor items should be equal, there should be some room for experimentation and for gimmicks to be planned.
