A little more conversation

I've been working on making tribe members feel more like unique individuals. To this end I've implemented character traits, which can increase or decrease stats like strength or intelligence.

Additionally, the people will now have conversations while idle, and these conversations serve to build relationships between the individuals. The traits can influence the the outcome of these conversations, for example a joke made by a funny person will be better received than one made by a serious person.

Relationships between people are purely cosmetic for now, but I plan to make them have actual tangible effects in future updates.
