TiddlyWiki: bugfix for Firefox Quantum -- use HTML5 web storage instead of a Cookie

Browse source 
Firefox Quantum adopted the idiotic behaviour of Chrome and does no longer
retrieve Cookies for pages read from local file system. It stores the Cookie
data into its local cookies.sqlite, but it does not retrieve it anymore.
For aledged "security reasons", however it happily retrieves HTML 5 web storage

Since TiddlyWiki classic just accesses the document.cookie at 3 points,
it is easy to patch around that problem. Just check, if we're using a modern
browser with support for HTML5 web storage and branch accordingly.
