This adds the baseline infrastructure to account for the Sevii Islands, while also fixing a couple of bugs. Zeta, please read the commit carefully!
Only real issue I noticed was that scrolling on the town map is infinite in all three new regions, implying there's something in `pokegear.asm` I haven't accounted for.
I've also ret'd the ezchat order and gen1 orders out of existence to reduce the sheer amount of 8-bit warnings. This abolishes gen1 compatibility (though this was already a bit fucked) in exchange for actually being able to debug things in a reasonable timeframe.
This implements Old City, the Honey Grandma's House, and its Pokecenter+Mart. Bunch of other bits and pieces not added yet, need to figure out the lore for them.
Honey Grandma is designed to make it easier to get important Pokemon, rather than give access to anything new. Thus, she's Nihon-locked by being an Old City resident. Martha's Perfect Rod will follow this trend.
Gold Berry tree exists to make them renewable in-game, I think this is very important.
The flypoint seems bugged.
