needs to choose word selectors based on environment

we possibly need more UI components to allow the player to choose preferences for the generated name..

Exactly what types of names are we expecting this script to generate? Each type will likely require different parameters.

Notably, naming a Unit depends on whether it's an "Outsider" or if it belongs to a Civilization - the former will pick from the word selectors in df.global.world.raws.language, while the latter will pick from the ones in entity_raw.symbols.
