GHC'19: add persistence layer so users can log in and save progress about keyboard-shortcuts-practice HOT 2 CLOSED

@alodahl I was chatting with someone at one of our Open Source Study halls, and I wanted to clarify this issue/requirement.

If the only reason for the persistence layer is to preserve user progress between sessions, switching from sessionStorage to localStorage as the mechanism for preserving progress would meet this requirement, with a couple of caveats.

• progress would be only saved within the context of a given browser. So, switching browsers or computers would mean that the user is starting over;
• clearing the browser cache would reset progress;

If this is sufficient for persisting progress, #55 should address the issue. If not, then could you say a little more about how you would like to save/persist progress?
