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 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.
