Default save folder on windows when running an .exe version doesn't work
The default identity seems to be the name of the file that's being run. So when running the source, it's "game", when running the .love, it's "game.love" and when running the .exe it'll be "game.exe". However, some windows versions seem to refuse to work with such a folder name.
Maybe the default identity, it not set through "love.filesystem.setIdentity" should be game_exe, or just game - even when running a compiled .exe.
