Support better handling of breadcrumb trails late in the page, where $post might have been stomped by the theme or plugin.
      Prep work for the 1.4.4 release:     Updated compatibility statements.     Compatibility verification with WordPress 3.9.1 and third-party plugins.     readme upgrade notice.     Updated translations pot.     Update plugin php version number.
      Optimize a couple of other calls to queried_object.
      Use cached queried_object instead of global $post.
      Cache get_queried_object in the generator.
      Call an init function whenever the generator is created.
      Create the generator right at the get_header hook.
      Allow the instant breadcrumbs object to cache a generator.
