oneSafe evolutions with oneSafe 3, oneSafe 4 and oneSafe+

When oneSafe 4 was released in 2018, oneSafe 3 was discontinued and was not supported anymore.

Now, we released oneSafe+ as an update of oneSafe 4 and we wanted to allow our oneSafe 3 users to get the new features without having to install a different app: oneSafe 3 has been replaced by "oneSafe", without the "+" features you can have via in-app purchases.
