Save concptarium URL with local cookie

[issmirnov]

Currently, I have this deployed via docker on a personal server. On every page refresh, I am asked for the url of the conceptarium. It would be useful to have this URL saved in local cookie storage.

Good point. The Streamlit framework itself resets the session store on page refresh, with apparently no easy way around it atm. But it could be saved locally in a text file or something. Will look into it, probably sometime this month.
