Green Mod (1.0)

In my Mod you can simply plant a new forest just with a worker. I like to have a green empire and maybe some others do so too.
It´s compatible with Civ4 1.09 Version 1.0 changes: * Made forest plantable with worker after tech paper. in epic speed, one worker needs 30 turns to plant it * reduced production gain of forest cut from 30 to 20 * increased forest and jungle
