Automatically create quicksave before quickloading

[Untribium]

It would be nice if the game automatically created a named quicksave right before loading another quicksave, so that, in case it doesn't take you where you wanted to go, there's a way to go back.

Also, this probably sounds kinda silly, but it would be nice if the game saved 2 quicksaves instead of only one (meaning it always keeps the last two quicksaves) so that if you hit F5 by accident, you don't lose the other save. Sure, you can name them, but in case you forget, this can be really bad, especially if you mean to hit F9 because something went wrong and you hit F5 instead...

Should be really easy to implement and could potentially save a lot of time (and rage )

Also, is the autosave always the persistent.sfs?
