Home field grass/dirt type

[Turd]

I just added a little tiny bit of flair to the stadium code, basically, you can choose if you want modern dirt paths or retro style dirt islands like are on the original game...so, if your team is the home team, your game will be played in a park with whatever style you chose.

Everyone is defaulted to "modern." If you want retro, please post here and I'll make the change...
