just in case.

Jb50821 transient notifs

See merge request !150

Currently, marking a notification as transient means it will be
closed immediately after it is presented to the user in the
notification preview. However, it should also be prevented from
appearing in the notification list even while the preview is shown.

Set transient where necessary.

These categories are unused:

x-nemo.connectionselector.wifi.conf

Leave appIcon as the only icon-related property/hint in the API, and
define it as HINT_APP_ICON.

  appIconChanged, and remove setAppIcon() so that it is set
  with hints instead
- Remove previewIcon and deprecate HINT_PREVIEW_ICON
- Remove icon and deprecate HINT_ICON

Notification category .conf changes:
- Use app_icon instead of x-nemo-icon

Previous approach of having nextUser as next user's name in

to uid of the user whose information should be shown on ShutdownScreen.
