On: Phones should have a 'guest lock' feature

[MrDresden]

Due to the intent system on Android allowing a pinned application to open another one (for example by sharing something), I prefer instead to create a guest user and add the app in question to that account.

That way no other applications are available to open, accidentally or otherwise.

I tested it and it blocks opening other apps when pinned. Maybe blocking app opening doesn't work for apps using some older system APIs.
