Add Syndetics AuthorNotes, Awards, Series

This patch also includes a new function to retrieve the index
page from Syndetics and parse it for available content prior to
retrieving content; this is done to speed up syndetics content
by not retrieving content that doesn't exist for an item. However,
Syndetics continues to be a very slow service compared to Amazon.com
and other enhanced content services
