[PATCH virt-viewer 18/25] Add VirtViewerDisplay::selectable property

[Marc-André Lureau <marcandre.lureau@xxxxxxxxx>]

This property will be set when the display can be selected to be
"enabled" and shown (this can involve creating/connecting an
additional guest monitor, and may need guest agent cooperation for
example).
