added the Traitor role/alignment
the traitor is an innocent, but works for the mafia. they have access to the mafia list, but the mafia doesn't know who they are. the traitor only wins with a mafia victory. its goal is to deflect suspicion from members of the mafia and cause confusion.
also added the Jester role, adapted from the clown, and moved the clown into more clear joke role territory, having a chance to transform from the jester if it appears.
the jester is a cut-down clown who wins by being killed. they do not have a gun, a horn, two lives, or a push ability. they must be killed through their own ability to bring suspicion upon themself.
