[Suggestion] Local integers/booleans

[Someone671]

Opposite to global integers/booleans, which saves across saves.
Basically, it's like global integers/booleans, but it saves to that save, so if one starts a new game, that variable will be reset.

An example would be a mappack, where there are puzzles which the player must solve all of them to win. The end of each puzzle is a button that sets the global boolean to indicate such puzzle has been solved. This means it persists through quits and files, but also means the player could only have 1 go, since if they enter it in a post-finished state, the exit would open up, ruining the fun. A solution would be to have a reset button, but just resetting it all at the start of a file is better.
