This allows the ObservableListAdapter to be garbage collected along with
its activity. On the next list change, the OnListChangedCallback will
detect that the adapter is gone and clean itself up. This avoids needing
to manually remove the list from the adapter, as would otherwise be
required to break the reference cycle adapter→list→listener→adapter.
This will be relevant once the list of profiles outlives the activity.

For now, it simply reads the files in the app's data directory with
file names ending in ".conf" and displays them in a list.
This includes the generic list data binding setup for future use.
