Merge #371: Remember user's peer sort preference

9cd558e qml: remember user's peer sort preference (jarolrod)

Pull request description:

  This sets the sort preference for the peers table in qsettings so that
  it can be remembered. Also addresses an issue where the `id` toggle button is always checked when you go back to the table even though the table is not sorted by `id`.
