Yellow squiggly lines begone!
Done automatically on .cpp files through `run-clang-tidy`, with manual corrections to the mistakes.
If an import is directly used, but is technically unnecessary since it's recursively imported by something else, it is *not* removed.
The tool doesn't touch .h files, so I did some of them by hand while fixing errors due to old recursive imports.
Not everything is removed, but the cleanup should be substantial enough.
Because this done on Linux, code that isn't used on it is mostly untouched.
(Hopefully no open PR is depending on these imports...)
AchievementBox now has UpdateData and UpdateProgress, which is called from UpdateData, but may be called elsewhere to update just the progress measurement of the achievement.
AchievementBox is an extension of QGroupBox that contains the data for a single achievement, initialized with the achievement data and able to reference AchievementManager to update itself.
