- events now follow a public const member pattern instead of getters
- more file utils
- ModInfoLayer split into LocalModInfoPopup and IndexItemInfoPopup to reduce uses of ugly variant
- same with ModCell
- lots of restructuring related to UI anyway
- Index also got tons of redesigning
- much more i've forgotten
- this commit compiles, surprisingly enough, but it's not usable as installing mods through index was removed
- remove duplicate LevelSearchLayer ids
