- `PSYCHIC` → `PSYCHIC_TYPE` (not the trainer `PSYCHIC_T` or the move `PSYCHIC_M`)
- `BLACKBELT` → `BLACKBELT_I` (not the trainer `BLACKBELT_T`)
- `CURSE_T` → `CURSE_TYPE` (not the move `CURSE`)
- `TOWN_MAP_D` → `TOWN_MAP_POSTER` (not the item `TOWN_MAP`)
This also uncovered a misidentified event: `EVENT_DECO_PLANT_4` → `EVENT_DECO_POSTER_1`. (There are three plants and four posters.)
The previous name for this was rather misleading. It isn't an actual
jump like you'd expect the `jp` instruction to behave as. Instead, it
behaves more like a `farcall`.
This also makes it consistent with its current command ID name of
`TX_FAR`.
Renamed `game` to `games` and `menu` to `menus`.
Moved some functions from `engine/routines/` to their fitting subdirectories.
Made two new subdirectories:
* engine/rtc: Contains all RTC-related things. Menus, hardware, misc
functions.
* engine/items: Contains all item-related things. Pack, item effects,
other item handlers.
