This is an informed attempt at reorganizing the engine/ directory by creating categorized subdirectories, in order to make it easier to navigate and find things. The directories created are as follows: * engine/game: Contains all "minigames", things like the unown puzzle and slot machine. * engine/gfx: Contains all handling of graphics. From loading palettes to playing animations. * engine/link: Contains all multiplayer functionality. * engine/menu: Contains all generic/misc. menus and menu code. Other, more specialized menus are in their own subdirectories (pokedex, pokegear, party menu, etc). * engine/overworld: Contains all handling of the overworld. From loading and connecting maps to wild encounters and the scripting engine. * engine/pokegear: In the same vein as engine/pokedex, except it could use some more splitting up. * engine/pokemon: Contains everything related to manipulating pokemon data. From the pokemon storage system to evolution and mail. * engine/printer: Contains everything related to printing things as well as the printer communication. * engine/title: Contains intro sequences, title screens and credits.
