QuickSettings: FavContact & UserTile: Open full contact page

QuickContact popup can only be used for phoning/messaging/emailing,
which doesn't make sense when you're opening your own contact.

Opening the full contact directly makes it easier to beam or share
with other (one less click)

Also added this change to include FavContact

Set foreground priority for shutdown receivers.

The broadcast of ACTION_SHUTDOWN has a timeout of 10 seconds. To
reduce the risk of hitting the timeout and speeding up the
shutdown sequence in ShutdownThread we set the priority of the
BroadcastReceivers to FLAG_RECEIVER_FOREGROUND.

We have seen that this change reduces the shutdown time when
the system is under heavy load.
