Add debug log message to print each bar's widget tree

Browse Source 
This is very useful when writing CSS that affects more than just a
single widget. Pass `-l debug` to enable debug logging and show this
information.

Example output:

    [2020-11-30 12:38:51.141] [debug] GTK widget tree:
    window#waybar.background.bottom.eDP-1.:dir(ltr)
