Nihon Route 49, Folage, and Barreau

This commit adds Nihon Route 49. It has everything necessary to work, but the wild Pokemon don't seem to spawn. I've added infrastructure that should allow this to happen, and it works for Kanto, so I am presuming that some other tomfoolery is at work.

I've also added Folage and Barreau, and implemented Folage into the Headbutt Tree table. This was to give them to the Bug Catcher on the route.
