Add option to reset launch version automatically when uninstalling an update

[grady404]

Feature description

Create a setting that can be toggled that will reset a game's launch version automatically every time update data is uninstalled, or a different update is installed that overwrites the existing one.

Benefits

I use Goldleaf to switch between different versions of a game, and this would make it a lot more convenient to switch, since there would be one less step involved every time.

Additional information

The launch version should also be reset every time a different update is installed that overwrites the original one. It shouldn't be an issue to reset the launch version even if the new update being installed is more recent than the existing one, since the launch version will be updated again as soon as the game is launched regardless.

If you see it fit, you could even make this option the default. I don't see any major drawback to it, although I suppose some users might (for example users who play a game that would corrupt the save data if opened on a previous version, although I don't really see why they'd be uninstalling update data in the first place).
