Per discussion on pret, `obedient`/`fatefulEncounter` has been renamed to `eventLegal`, and all related functions and constants have been modified with this in mind.
Additionally, fixed some whitespace alignment issues in `script_cmd_table.h`, `pokemon.h`, and `tv.c` from the last commit.
The giftRibbons field has been split out into proper subfields. The new ExternalEvent structs deal with interconnectivity between external games/peripherals and Emerald, such as PokéCoupon storage and the flag for receiving Wishmaker Jirachi.
The giftRibbon fields in `PokemonSubstruct3` have also been renamed to their appropriate ribbons, and commented with distribution info if applicable. The previous `fatefulEncounter` field was actually filler, and relabeled as such, while the obedient bit was renamed `fatefulEncounter`. All relevant constants and functions dealing with the Pokémon data structure were renamed with these changes in mind.
