finally update dunst to >1.7 configuration

Config adapted based on docs:
    https://github.com/dunst-project/dunst/blob/master/docs/dunst.5.pod

And the somewhat controversial original issue :
    dunst-project/dunst#940

For now just using a hardcoded gruvbox, as making the theme adaptive is
a bit cumbersome
