Zoom Closer per Puneet Arora

Automatically closes the Zoom Post Attendee window that is created when launching a Zoom meeting from zoom.us. Uses Chrome Context Script to send a message to a background page to close the tab. Requires no special permissions (except access to the page 'https://zoom.us/postattende' and 'https://zoom.us/j/*).
