Use #/settings in user popdown panel

Instead of linking to /settings which causes a GWT UI reload,
use #/settings allowing the UI to be replaced. This fixes a
visible glitch when clicking Settings in debug mode and Buck
is kicked off to update the JS code, and even in production
installations when the server is far away from the user.
