Make DisplayEndScreenForAllMaps setting on by default

Submissions to goldberries.net require this property to be on, and apparently IL submissions to speedrun.com do as well. To me, it makes sense to have this property on by default, since there isn't really any downside other than being slightly less "seamless" when you complete a map. The upside is that it would save the mod team for goldberries.net (and possibly speedrun.com, idk) a lot of headache of having to reject or add notes to submissions that don't follow the rule because the option is off by default and people don't read the rules.

I would have made a PR for this but I don't have write access to the repo, I already have the change made on my local copy and everything.
