This adds the ability to load a board with the menu hidden; it provides a form of "read-only" mode, but the key bindings are still active.
Use with, e.g.:
http://localhost:5001/boards/qYAZyGdym6HqjnfaGI4yNtpdx0IMHd9qp6kaJPwbJqE-?hideMenu=true

The alternative, proposed in #116, was to remove the menu completely, but this would require more substantial changes to board.js (which hangs on "Loading..." if the menu is removed).
