The long-running service is needed for keeping track of which profiles
are enabled, for showing notifications, and for the tile service to use.
Since it has to know which profiles exist anyway, moving the main
ObservableList there avoids some code duplication. It ensures the list
is only loaded once, so it cannot get out of sync. It also makes the
ProfileList activity load faster, because it doesn't have to wait for
file I/O; and it provides a canonical place for storing the Profile
objects so they are accessible everywhere, instead of having to look
them up by name.
This does present some challenges with leaking activities, because all
listeners must be removed from the profiles list (and its contents) when
an activity is stopped.
