[READY] Adds station traits: Small modifiers that can randomly be chosen each round (#56309)

This PR adds station traits which are essentially small changes to a normal round that can be used to create small variations in how a round might play out, sometimes there might be only one, very simple trait, but you might have a round where they have a somewhat bigger impact, to make rounds feel slightly more different from each other.

The following traits have been added:
Positive:

    Lucky winner - Free pizza and beer every 6-12 minutes
    Galactic Grant - Larger starting funds for cargo
    Premium internals boxes - emergency box has flare + radio as bonus
    Bountiful bounties - Bounties pay 20% more
    Strong supply lines - Imports 20% cheaper
    Filled maint - More loot in maint
    Fast shuttle - Cargo shuttle is faster
    Free scarves - Free scarfs if a slot is free

Neutral:

    Bananium shipment - Clown starts with 5 sheets of bananium (Neutral because this helps noone but the clown)
    Unnatural atmosphere - Lava planet can get more restricted gasses
    Unique AI - Random lawset at roundstart for AI
    Ian adventure - Ian teleports to a random spot on the station
    Glitched PDAs - PDA's have a different beep
    Announcer intern - Changes the announcement messages to sound like they're from an intern at Centcom

Negative:

    Carp infestation - Carp event is more common and can start earlier
    Weak supply lines - Imports 20% more expensive
    Blackout - Station lights are partially broken around the station
    Empty maint - Less loot in maint
    Overflow bureacracy mistake - Random overflow job (From a vetted list)
    Late Arrivals - Everyone starts in arrivals
    Random spawns - Random spawn location (by drop pod)
    Slow shuttle - Cargo shuttle is slower
