add "Remember Code" checkbox to web console

Hi, it's Freakishly Tall Dave from GR8Conf last year.  I've added a checkbox to the web console that remembers whatever code was last executed in the browser cookies.  I got tired of copying off my code and always having to put my imports back in (if nothing else) after a laptop shutdown.

Hope you find this worthwhile.  Be well!
