Allow settings to skip Splash Screen (and just launch the main form without fuss, cuz why not?)
Handle scenario where PKHeX.Core.dll fails to bind during Settings fetch -- handle via static constructor instead of Program.Main() so that errors pipe to the Release error handlers.
Run update check in another thread, after Main is shown, so that offline users don't have to wait 3 extra seconds for it to timeout and show.
Revise the startup animation to just show the Main form rather than minimize->restore. The previous "hack" was designed so that if users clicked anywhere after launching the program (thus losing focus) the Main form would re-capture it. Activate() works fine now (maybe it didn't in the past?)
Removes "dark" startup arg; do via settings. Users really won't have a separate launch config like they might for HaX via .bat
Allows specifying Dark mode in settings now.
Extracts reusable settings objects to PKHeX.Core (drawing/GUI stuff kept in WinForms).
Updating settings now refreshes backup paths/mgdb
