Allow the passing of the post ID ('post_id' arg) for getting a specific post's media.  This also means we dropped get_the_content() in favor of get_post_field() for grabbing the post content since it supports a specific post ID and doesn't assume we're in The Loop.
Update deprecated post format functions to return the correct post format functions.
Update breadcrumb labels to handle time-/date-based archives.
Update search results title to match breadcrumbs with quotes.
Use %d instead of %s for date strings.  Also, use get_query_var( 'w' ) for outputting the week number.  get_the_time() adds a week for whatever reason.
Use '%s' over '%1$s' where appropriate.
Switch back to date_i18n() and get_the_time(). If this is a problem in WP, it needs to be fixed there.
