Suggestion: Change the additional tile priority

[SSLConf_Stalker0]

When adding a new tile to a city (at 8 pop and greater), the city autochooses your next tile. You can change it (with a brilliantly simple UI btw), but I think a smarter tile selector would be good for the game:

1) I have seen cases where the selector will choose a mountain over a mountain with the gold on it. Selector should always choose a special resource if able.
2) Sea tiles get a lot of priority. This probably made sense before the new improvement system, but now land is simply better than sea in almost every case. The prioritizer should choose land tiles over sea.
3) The prioritizer seems to focus on forests when your pollution is high. Since forests are easy to grow, I would rather it focus on the core tile. For example, I will take a grassland I can make 3 food over a 1 mineral hill with a forest on it.
