Subject: [PATCH] Automatically update the lists of current games and actions.

Add some window.*interval() code to getcurrent() so it will register
itself as an interval and clear this interval when the list is not
visible (i.e. playing or watching.)  It also calls getchoices() if the
user is logged in, so that will be updated as well.
