notes on first release

• initial idea was to make tabgod function available in all devtools consoles for easy and direct access for developers right from every console
• the implementation added tabgod to the global window object
• however this introduced a serious security issue, since this has made the function available to websites also, allowing them to interact with other tabs, destroying the idea of secure tab origins
• thanks to danielsmc pointing it out
• this has been immediately addressed by moving the function only to the options page of the extension, and not accepting external connections in the service worker
