Fix cursor for menu items, add event ctrl to menu

Re-add "href='#'" to menu links to ensure browsers do the right thing
with cursors.  Add `preventDefault` calls to event handlers to avoid
unnecessary hash urls.

Add start/stop event menu item to the "Event Settings" menu; augment API
handler for starting/stopping events to function with AJAX calls for
this purpose.

Make start/stop events and start/stop sessions menu items conditional,
so that only the relevant one is enabled at any time.
Switch how-to-unhangout to pre-scaled images
