Animal name generator tweaks

[dkambersky]

Right now the animal name generator works, but

• [x] the sourcelist combines both male and female names in one file, so the names at times come out a combination of those. There should be separate source files for both sexes.

• [x] the animals get surnames from the same sourcelist. They probably shouldn't even have surnames.

This is a simple change for someone with the workspace set up, I'm noting it down so it doesn't get forgotten.
