[Sugar-devel] rethinking your icon customization patch

If inotify is available it will use that I think. Checking time is an
option for the sugar cache (file content) but not for the gtk one (file

Perhaps it's fine if the change is picked up on activity restart? It will
probably not auto apply anyway, only newly created icons will change even
if the caches are invalidated.
