Send desktop notifications when user joins group (fixes #6)
Send desktop notifications when user joins group (fixes #6)

Previously, if somebody joined your group while you were
on a different window/tab, browsers wouldn't play the other person's
video, so you would have no idea that they joined.

Now, tawk sends you a desktop notification (and sound effect)
if somebody joins your group while you are on a different tab.
