Increase abstraction for arbitrary slot get/set operations, and fracture
SAV4 behavior for each game type.
Adds: Undo/Redo of party slot changes
Fixes: Fixed Gen5 daycare slot 2 reading, and EXP reading
Fixes: Some slot color glitchiness
Fixed: Box layout editor now hides the flag label if no flags are
present
Fixed: Gen7 box flags are now shown (unknown purpose lol)
Changed: savefile objects are generally smaller (removed a few shared
offset fields)
event move only
still haven't bothered finding the table in the exefs that results in
the pkm with an oob move being dummied. hardcoded based on data for now
:)
LGPE will missingno your pokemon if it's not a Kanto/M&M, or one of its
moves is not obtainable. For the user's benefit, filter down these
sources to the non-baddata list.
Item filtering and ball filtering might be something to think about for
the future, but not much benefit vs effort.
