Grass Stains for Drupal 4.7

I've worked recently on a port of the Grass Stains theme for Drupal 4.7. Though it is not quite perfect it seems to work well for most things and I don't have the time at the moment to track down the last few glitches. If anybody is inclined to pick it up and add anything more please do so. If not it will likely stay as-is for a while.
