Comment 20 for bug 1358340

So we're basically looking at it as three levels:

1) Everything on lock screen. You like that, dont' care.
2) Reduced data, stuff is there, but it shouldn't be a really egregious leak or control things.
3) No Indicators

Basically the "MessagesWelcomeScreen" toggles between the first two. Then the no indicators setting will turn on 3 or not. So for those who are very worried about security they can turn off indicators entirely. For those who'd like them to be a bit more restricted but still available we can reduce the data set. And for those who live on a desert island by themselves they have the full monty option as well.
