Clowns, Rough morale trap framework, clown phobia and philia

Clown zombies that HONK softly to attract other zombies to your
position. Mostly a silly, not very good at combat, zombie, but can
hamper your combat ability if you're afraid of clowns. Adds in a Phobia
that will damage your morale if you encounter a clown and hear it honk,
and a philia that gives you morale boosts in the same way as fancy
clothes do to stylish characters.

Also adds in rough framework for a morale trap, for gruesome scenes,

Morale trap will be modular/scaleable via trap difficulty, so it will be
somewhat easy to change around how much it really affects you without
having to delve any deeper than a .json
