reduce notification spam in volume/brightness

Added a second parameter to notifications (actually a first, "app-name"), so they can be *grouped* when there is more than one, reducing the clutter on the screen, using the mako config parameter " group-by=app-name "

with proper quotes (i hope), case and cute icon ;)

added "group-by = app-name" directive in mako config
