Replaced encounter rates with percent values
Added new constants denoting the number of wild Pokemon in the grass and water wild constructs
Annotated and relabeled the encounter generating functions
Renamed a WRAM address associaed with the temporary storage of the wild Pokemon's species
Moved spawn constants to constants/map_constants.asm for use anywhere in the disassembly
Wram banks and mobile make this tough, since any address can secretly be a ghost.
As usual, mobile completely disregards 99% of the codebase. It's been ignored in kind.
