Alerts you to the number of unread items in Google Voice.
See original script at http://userscripts-mirror.org/scripts/show/55234 written by Peter Wooley.
Updated to support the revamped Google Voice interface at https://voice.google.com/ .
Script will now detect unread messages, calls, voicemails, and archived unread for the new Google Voice interface and draw the number of items over the updated Google Voice favicon. Drawn unread count is now moved down just a bit as well to block less of the new icon.
11/11/2020 - Updates to support latest google voice page with updated google voice icon as well.
02/02/2024 - Updated to reflect class name changes and minor change to script header for future compatibility (use @match for url regex).
