I think the style guide lightly discourages classes that are merely collections
of static functions [1]. Although here you could argue that these are tied to
the AppWindowRegistry class (although without needing friend access).

I think I like how it looks now, but could be swayed easily accept a namespace
(or even global functions..).

I introduced this AppWindowRegistryUtil class because I was too lazy to coin
function names which make sense without the class name in the global namespace
:-/
But, it seems these function names are descriptive enough so it might be OK to
put them in the global namespace.

Though I feel a bit hesitant to put them in the global namespace as it's
generally not a good idea.
Maybe they should be put in a namespace "apps"? (no file in chrome/browser/apps
is using namespace "apps", but files under app_shim are using it.)
