Remove/replace/rebalance rarely used traitor items

[Mouse]

Since goonstation became open source a lot of new traitor items have been added.  Some of them get used.  Some of them don't.  To prevent the list of traitor items from getting cluttered with stuff people don't ever buy, it might be a good idea to look at the rarely purchased ones and either remove them, replace them with a conceptually similar but better version (i.e. the chameleon outfit set for the chameleon jumpsuit), or rebalance them, making them stronger or cheaper or both.
