Added typedefs: mapsec_t, metloc_t, and variants for MAPSEC and METLOC values. There are some rough edges that could do with smoothing out, but for now, this gets us close to ideal with a ROM that compares equal.
Per feedback, all typedefs to mention the underlying type within the typedef name. The documentation comments reflect and explain the naming convention.
Updated comments to reflect the fact that we're no longer using SET8 for a Pokemon's met locations, in favor of a new macro (added by this PR) that adjusts to match the width of whatever is being set.
- Determined how the various script contexts were used and renamed accordingly.
- ScriptContext2_Enable/Disable => Lock/UnlockPlayerFieldControls - The sole purpose of the flag is to make sure the player can't move around in the overworld. It has nothing to do with script contexts.
- ScriptContext1 => ScriptContext - It is the global script context used to set up scripts which run over many frames.
- ScriptContext2_RunNewScript => RunScriptImmediately - ScriptContext2's sole purpose was to run scripts immediately and in a separate context, usually while the global context is waiting for things like map loads or screen changes.
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.
