visibility logging does not handle animation change during view

[7yl4r]

The viewLogger (in avatarWallapaper) responds to onVisibilityChanged() and then prints the time viewed along with the current animation, it is assumed that the animation at end of view time is the animation which was present the whole time. An example of when this breaks: I turn on phone screen, animation is running, while I'm looking at it the animation changes to sleeping. Now when I turn off the screen, the logger records that I viewed 'sleeping' for the full duration of my use.

This is probably not a big deal, since animation changes occur infrequently and view times are short, so the chance of seeing a change is rare.

In order to fix this, the logging should be broken out into a function which can then be easily called from within the timed scene changer as well as onVisibilityChanged.
