problems by adding new racial traits

[PvK]

1. If you add racial traits, you'll need to add them to the bottom of the racial traits file, or it will give errors when it tries to load old empires with racial traits.

2. After you make a mod and start a new game with it for the first time, sometimes the map doesn't show up the very first new game. I forget exactly what the cause and real fix are, but the workaround is simple and once-only: just save the game and then re-load it, and the map will appear.
