Some new flyers!

Clueless CDC public safety message, ominous FEMA message, rambling
conspiracy-nut-who-was-actually-right-for-once pamphlet, crazy religious
person chastising everyone for being sodomites message, crazy cultist
who wants to be eaten by Cthulhu message, scary
the-Army-is-not-your-friend message.
Cultist flyer->cultist note.
