Mirror pokeemerald PR#1329 & PR#1335 to pokefirered

The `giftRibbons` field in `SaveBlock1` has been split out into proper subfields. The new ExternalEvent structs deal with interconnectivity between external games/peripherals and FRLG. US & JP Colosseum Bonus Discs', Colosseum and XD's, Pokémon Channel's, and PokémonBox: Ruby & Sapphire's interactions with these fields has been documented.

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 `eventLegal`. All relevant constants and functions dealing with the Pokémon data structure were renamed with these changes in mind.

I still maintain that `eventLegal` is a misnomer and it should be called `fatefulEncounter` in all three repos.
