Spruce up Viridian Forest

[B13rg]

Make a few changes to make viridian a better place, instead of a shadow of it's former self.

• Make the forest a separate map, or atleast as large as it was in gen 1
• Add evolutions of team rocket pokemon to the forest. In the manga, team rocket used the forest to breed and train pokemon for their troops
• Add small lake/river to the forest
