This aims to make future refactoring easier. The arguments are removed where possible, but kept and marked with C++17's [[maybe_unused]] where they could not be removed (e.g. when they are used as a callback, rather than called directly).
I've skipped the rides/<category>/* and peep/* source files, because the rides source files are mostly generated and have a ton of unused variables, and the peep source files are being refactored.
I've also skipped most of window/* source files, because most of the functions are used as callbacks and will be bulk-renamed at some point.
Change min energy cheat to the correct min value 32. This fixes the issue with the min energy cheat that causes it to reset to 255 a few seconds after applying it.
This uses a previously unused S6 flag to save this option persistently.
This should not make S6 import much harder, but should reduce the amount of questions about S4 import.
Also refactor the checks whether the user can ask money for rides or entry. This should make it a lot easier
when our own save format comes around.
