this removes submodules and external libraries in the code in favor of
importing them as CPM packages. CPM_SOURCE_CACHE is recommended as
codegen has to readd two of the same dependencies
- 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
- rewrote Loader to have a public loading API
- moved logging away from Loader
- moved texture path handling away from Loader into CCFileUtils, added new functions there for that
- bumped version to v0.7.0
- moved ModInfo to its own header
- added early loading support through mod.json instead of loader stuff
- wrote a custom Unzip implementation (essentially same as ZipUtils except with a much more simple and clean API)
- renamed `src/load` to `src/loader`
- other stuff i prolly forgor
