[CombustibleToast]

Departmental clown masks are gone, sprites deleted and YML commented out. Loadout groups removed. Clown shoes removed from loadout groups. Clown mask and shoes removed from departmental drobes' contraband inventory. Botany and chef still can get the clown apron from the drobes' contraband inventory. Chaplain retains all clown apparel to fit the honkmother set.

don't look too hard at the diff size

Sorry review took so long but this looks fine. I'm gonna wait for sage to give it a 2nd look since it's so many lines changes but it should be good to merge

Missed some clown shoes here!

Matt is a liar and a fraud! Couple things on this,

You'll need to merge our main into your pr's branch to fix the conflicts. Should also fix the integration test fail for the ComputerFundingAllocationBroken since we've already migrated that I think.
But most of the integration test fails are from maps having these prototypes still on them:

You couuuld remove them manually if you'd like. But if you want to make it simple, just make a line for each in Resources/migration_qb.yml that migrates them to null or some other generic mask prototype.
