[virt-tools-list] [PATCH 18/22] app: create a window for VTE displays

[marcandre.lureau at redhat.com]

From: Marc-André Lureau <marcandre.lureau at redhat.com>

virt_viewer_app_display_added() now handles VTE displays. They should
be skipped for monitor configuration, and they don't emit "show-hint".

(a VTE display has a monitor nth == -1, which is now a valid value)

The associated window will be hidden when virt-viewer is started.
