Lots of things here. Citrine now has its own tileset featuring content from the prototype asset leak. This includes new grass, signs, and so on. Lots of tinkering had to be done to make it look good, but it does! Collision and everything is done, but grass needs to animate properly. I'm committing as-is because making the grass animate is actually very difficult.
Also added the Metal Coat and fixed the issues with prior evolution methods - evo items first, level-up second. It is currently unobtainable.
Added map data for Citrine City, including wild spawns, as well as a fly location. Also fixed an issue where Bill's Garden couldn't spawn wild Pokemon. Citrine is also green for some reason.
