Add support for almost all Gen III games

The only Gen III game unsupported should be Pokémon LeafGreen v1.1
(Japan); as it is undumped.

A couple of bugs have also been fixed.

The code has also been refactored a little; now payload code goes into
`payload.c`. The codebase is also ready for a planned future change to
include savedata structure definitions. This will be done when it's done
-- PRs to help would be appreciated!
