Feature description

As previously discussed in #250, when the "screen lock" option is on, the "screen security" option is also forced on and then greyed out.

Can we return this choice to the user? Signal already allows this, and many other apps have similar settings, for example Firefox has an option to allow screenshots in private tabs.

Of course there are many different ways people use a particular program, that is one reason why we have settings... I don't see any harm in letting the user choose to allow screenshots when also using fingerprint lock, I think this is a quite common use case and the alternative is much more cumbersome (turning the option off, making the screenshot, then turning it back on, every time you want a screenshot).

I don't think it is reasonable for people who want this to have to setup and maintain their own entire CI infrastructure to comment out one line of code, especially if they're not a developer.

Can we find a compromise somewhere to allow this?
