Feature Add: Trade interaction

[com1clyf3]

4. Trade, interaction with other races. Differentiate the other factions better with their repertoire of phrases and the ways that you trade with them.* Eliminate the notion of a “faction” altogether and just use the race as a proxy for faction. Add a couple more interactions with factions besides trade and war. (What are they?) *These aren’t storylines per-se, but more like standard interactions you can have with factions.

For the factions phrases and such - that's in. I rewrote all their dialogue in the conversion to yarn spinner. They are distinct, and more importantly, consistent internally.

I am currently working on "off screen interactions" with other factions. It's a bit more complicated than I hoped, but it should add a few more ways of interacting with factions and better way of visualizing them.
