Framework change for #2583442: Navigation dies when night mode changes

Browse Source 
The window manager doesn't retain its keep screen on lock while
in the process of destroying and creating new activity windows during
a config change.  Now it does.

Unfortunately, this doesn't help maps, since it doesn't use our
lovely KEEP_SCREEN_ON flag. :p
