#### BUGS (next-33)

BUG-6:		author does not have explicit ordering like sub-books... 
            - author inserts need author_num [DONE]
            - books on shelf now works with new code [DONE]
            TEST THIS - ITS A BREAKING CHANGE.... check every where I used
            book.author -> book.bals[]->author


BUG-7:		if you remove a series from a book, it won't appear in the series drop-down if it is the first 'missing' book in that series -- either reset the list, or show all series always?

BUG-30:     failed to add a book with 2 x same author (need to catch error
                or maybe mess with author list to remove duplicate potentials?)


BUG-31:     series does not have 'series_num', so a book in 2 series, means he ordering is not explicit
            -- UNSURE this is an issue, as 2 series would normally be 1 inside
            a larger one, and numbering implies the inner (smaller number), and
            outer has explicity overall ordering of books in both series, so
            should be ok?

BUG-32:     for book 1546 (with 2 sub-books, 1 with 2 authors), saving it causes 'series removal' dbox to come up 
            (no series though)
