[MERGED PR] Makes Stowaway a latejoin role

[Fuppy]

I'll be real, I think we all like how the stowaway trait works in theory as opposed to how it works in practice. In theory it makes for some interesting situations and RP where the person's legitimacy and reason for being aboard is questioned by the crew. In practice you knock on a door for five minutes and then someone sends you to the HoP desk to get an ID because meta-wise we all know whats up. The funniest stowaway interactions I've had are with staff assistants by far. Anything beyond that is just adding an extra step to the start of your round and not much else.
