[gnome-builder: 75/139] deviceui: add deviceui plugin

[Christian Hergert <chergert src gnome org>]

commit 36ebe876ada50afe4ca6467ae91078b95d59049e
Author: Christian Hergert <chergert redhat com>
Date:   Wed Jan 9 17:15:56 2019 -0800

    deviceui: add deviceui plugin
    
    This adds a new plugin to manage the UI components around device selection.
    Most of the device tracking is still in libide-foundry, but this deals
    with the UI bits such as the button in the header bar.
