Fix issue #2544466: Car Home brightness icon comes and goes while phone is in car dock in FRE83

Browse Source 
There was a really dumb bug that was causing us to not always apply
the new configuration.  As a result of fixing this, there were new
glithes in the transition between car and regular mode, so further
work here to fix that.  And since I was actually working during the
night and seeing night mode, I noticed how obnoxiously bright the
status bar is compared to the car home at night, so it now nicely
dims itself when we switch to the night config.  Oh and in doing
that I also found and fixed a bug in dispatching config changes to
a window (where they wouldn't get dispatched if the window didn't
resize).

FINALLY...  tweak the wallpaper enter/exit animations a bit to
make them a little smoother.
