Enhancement: Using storage.sync to sync pre-loaded cookies

Hi litetex,

nice extension ... I have a number of preference cookies (e.g. for startpage.com) that I'd like to keep synchronized across browsers.

Would you mind extending the cookie loader to provide an option to sync cookie definitions and that one boolen value from the options through the storage.sync mechanism?

I can try to come up with a PR if that suits you.

Thanks
