[gnome-boxes/troubleshoot-view: 7/7] app, window: Introduce troubleshoot view

[Felipe Borges <felipeborges src gnome org>]

commit 7a62b2db108e454de2c5f6ee79a6fecc2e84854f
Author: Felipe Borges <felipeborges gnome org>
Date:   Tue Jul 11 16:42:01 2017 +0200

    app, window: Introduce troubleshoot view
    
    Sometimes we are not able to launch the application due to issues
    down the stack that we cannot ignore in Boxes.
    
    This patch introduces an error message when Boxes is not able to
    start which allows launching GNOME Logs.
