feat(notify): add notify support

In this commit I added a new feature, a flag for notifications -n /
--notify. It's using the notify-send command line utility to send
desktop notifications. By default I made it compatible with dunst (you
will need to enable full markup in the dunst config) but it should work
with other notification daemons too.
