This change is to prevent browsers sending referrer headers from EtherCalc.
It fixes the scenario where a user clicks a link within a spreadsheet and their browser sends along the EtherCalc sheet URL in the Referrer header (allowing that site to view and edit the spreadsheet).
The meta tag is part of the Referrer Policy spec and already works in Chrome and Firefox.
Thanks for your work maintaining EtherCalc!
