JSON doesn't like trailing commas.

Make sure this is reflected in the flatpak manifest.

It's needed by E-D-S (and it's no longer part of the runtime/SDK).

Fixes https://gitlab.gnome.org/GNOME/gnome-contacts/issues/140

We need to wait till the aggregator has preperd all data or else the
search result will be empty, which causes no contacts showing up at
the first search in gnome shell

(cherry picked from commit 398b0a1514b23b5afdb7cfdfa0fdbaef89b2aeda)

Since get cheese_widget_get_camera () and get_video_area () are not
defined static they are are exported but we don't have the function
signature, therefore this adds the header file with the function
signatures.

This is required to build with current libhandy

The addd signal on the camera_monitor is never fiered
if there is no available camera when coldplug () is called.
Therefore the button remains sensitive.

This was giving an annoying warning.

Apparently libhandy also added a HeaderBar type, which means this
clashes with that of Gtk.

Latest E-D-S requires a newer version, so the build is failing because
of it right now.

These build options are now set by default on Fdo 18.08.
