feat(gs/xanthous): Allow generating creatures with items r/3097

Add an `equippedItems` field to the CreatureType raw, which provides a
chance for generating that creature with an item equipped, which goes
into a new `inventory` field on the creature entity itself. Currently
the creature doesn't actually *use* this equipped item, but it's a step.

This commit also adds a broken-dagger equipped 90% of the time to the
"husk" creature.
