- book 4 and also 1 of another (sub) series has up arrows disabled and shouldn't

alter a condition, covertype, etc. and its not in drop-down list (even though db look via index is correct, e.g books.html shows updated covertype)

moving a book (with sub-books) up/down in series will fail as the book_id is not in the book_series_link
	likely logic... for each sub-book... swap new book with sub-book#1, then for all other sub-books, up/down by 1

series does not deal with calcd_rating... 
	(on edit could, recalc as a catch-all, and obviously if we change a single book's rating, we should re-calc)
