* Moves the Mystery Box activation into Event Constants. This means that now, the Mystery Box activation is handled in the save, preventing some jank from happening when resetting.
* The "don't switch off the box yet" variable is now always unset after entering a map. Meltan itself allows the variable to keep being re-set, which is super handy. Now, whenever you enter and exit maps, it'll work properly.
* Flying, using an Escape Rope, and using Dig, all now unset the Mystery Box. If for some reason everything fucks up, this'll fix it.
* Fixed a text bug with the scientist in Celadon University.
* Fixed a menu alignment issue with the Vermilion Beauty.
* Attempted to fix the Battle Tent exit. Failed. This is a really, really bad bug, hopefully this gets sorted sometime.
- Meltan is now loaded in engine/battle/wild_encounters.asm, allowing its level to be fixed at 5 and avoiding various glitches. This also fixed the "running from Meltan ends the Mystery Box game" bug.
- Candy Jar now gives a message when it's full, more transparent to the player.
- Fixed a bug where the increment text wouldn't load properly, it was very silly.
Rhyperior files are dummies and will need to be properly edited with sprites, Rhydon evo data, etc, but it (and the other files included) show that the trainer and pokemon sprite indexes have been separated, which allows us to add the other KEP mons
