[polari/wip/fmuellner/debug-instance: 2/4] app: Add --debug command line flag

[Gitlab Administrative User <gitlab src gnome org>]

commit 42807a3a6af6cecef92954006d07ec909fbc0407
Author: Florian Müllner <fmuellner gnome org>
Date:   Fri Feb 19 12:45:26 2016 +0100

    app: Add --debug command line flag
    
    It runs polari with a different application ID and doesn't disconnect
    when closed, so it allows hacking on polari while using it for chatting
    at the same time :-)
    
    Fixes https://gitlab.gnome.org/GNOME/polari/issues/24
