Show latest message first when more messages are present than will show without scrolling.
Currently, if you have a lengthy conversation in Messaging, when you go to that page, the messages window is shown, with the top-most message first. That's fine if there are only 1 or 2 messages, but as the conversation grows and the vertical height of the thread grows, it would be helpful if the most recent message showed first.
AKA, auto-adjust the messages field to show the most recent message first.
