CloudSync blueprint ON by default

[SoShootMe]

[This needs to be fixed only] because no players will think when they lost their blueprint “shit, I’m such an idiot, why wouldn’t I install a backup?” But more like “Factorio, it’s your fault that I lost now my blueprint!!”

I think the latter is the first thought whether or not you have a backup to recover the situation, and that is my point in a nutshell.

Cloud sync is per se not just overwriting.

Not in general, but for a given file, it seems that's all Steam's cloud sync does when the file exists on both sides. I can't see any indication of conflict resolution. There may be no satisfactory solution under Wube's control, because of limitations of Steam's cloud sync.
