This makes it so everything except Rhydon works properly. At this point I'm willing to have Rhydon not work, they can just evolve into Rhyperior instead.
Currently the move tutor is a little bit broken - the IDs are 1 above how they should be. Shell speculates that it's searching at the table starting from Kangaskhan due to the way the decrements shake up but it may just be making things more complicated than they are.
Big cheese code is `PrepareTradebackMoveList`, it's where things are mucking up.
Also, the code can be significantly optimised, as it's currently being adapted from the function above, `PrepareRelearnableMoveList`; It doesn't need to check levels, for example.
Note that the relearner functions properly, so use it as a reference. I may have removed something important.
Technically, we could have NO_MON as an entry which may make things shake out properly. But I'd rather have a proper fix.
- Move Deleter and Move Relearner are added, featuring updated code from Shin Pokered, which took the code from Mateo's Red++ hack. They replace the Trader in Celadon University. The code has been updated quite a bit to fit the modern standards of pokered.
- The Trader has been moved to the trade room in Cinnabar Lab, which is thematically appropriate.
- Eevee's L1 learnset now appropriately features Tail Whip; this was a mistake made by Martha when porting Yellow learnsets.
- Fast Text cursor slot is fixed
- New ROM Bank stores the new maps as it got full when adding the move relearner/deleter - Maps 21 will still have space though.
- WRAM has been fiddled with, please please read the notes if you edit the Move Relearner area, it needs quite a bit of space.
- Wild data for Mt. Moon and Route 22 has been tweaked a little bit.
