"Buff" Vision Traits (#636)

# Description

This takes Ultravision, Dogvision, and Normalvision, making all 3 traits
into our first set of "Neutral" traits. They now cost 0 points, but
still occupy one of the 5 trait selections. In the future we should have
a decent roster of Positive, Neutral, and Negative traits. If Death ever
finishes making Subcategories, we'll probably want to have Positive,
Neutral, and Negative be the 3 "Main" categories, and all subcategories
sit underneath them.

if I don't include some kind of media.
