* Clean up grayed out items in file select.
Tie personal notes saving to `OnExitGame()` to account for save scum resets.
Hide text input box (but not window) for personal notes when a save isn't loaded to prevent saving over a save's notes while in file select.
* Allow check tracker window to be visible and show the "Waiting for file load..." text in file select (ease of positioning).
* Fix key label text placement.
* Persist `areasSpoiled`, change trigger to `OnSceneTransition`.
Add `IsAreaSpoiled` for tie-in to Item Tracker.
Add `SetAreaSpoiled` to unify bitmagic.
* Add proper spoiling evaluation based on specific entrance IDs, or first check collection.
Add light yellow color for vanilla dungeon abbreviations to match the purple for MQ.
* Initialize `areasSpoiled` to 0, so 0 gets saved on file create.
* All new conditional statements around `GameInteractor::IsSaveLoaded()` were inverted. Fixed that.
* Change some c-style casts to `static_cast`.
* Few more cleanups, plus clarifying comment.
