 Bug Fixes
 =========
 - FIXED: On phone without keyguard security if screen was on but
locked the getting a message would launch the app into the foreground
rather than showing a lock screen message.
 - FIXED: When a new message or a status update comes in while phone is
on and not locked the app will launch inappropriately.
 - FIXED: Video preview going blank if the app is put in the background
for a period of time.
 - FIXED: Crash where app would start from oncreate due to a
notification intent be sent to the background by the intent manager but
would continue through the lifecycle on its way to going to the
background. (Finish instead.)
