Persist state through local storage

Cool project! It'd be really nice if the webpage could persist its state and content via browser localStorage. This would allow saving without having to export to html every time.

i do want to support this but i'm not sure how best to deal with deciding on each board whether it should present you the board itself or whatever you saved last time you had it open. maybe a load button on the toolbar...
