Title: Use localstorage to remember Web REPL history

This is in re: Issue #579: web interface: add possibility to save/restore session?

For capable browsers, your command history will be saved using localstorage. In older browsers, it will degrade gracefully using Modernizr.js so that you just don't get history but it still works.
