### fix to get this working with bs 5...
editing a book needs to use input groups
	+/- buttons (add/rem say authors) are in wrong spot / input-group
	* buttons at bottom are broken still
get rid of font-awesome and use bootstrap5 icons
sort through dataTables calls in books_for_series.html (ever called without base?) -- Maybe as part of an ajax call?

upgrade bootstrap, dataTables, etc.


#### BUGS (next-20)

### DB/back-end

### UI not updating after DB change:
BUG-3:		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)
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?

### ordering of data in UI:
BUG-6:		author,series, etc. do not have explicit ordering like sub-books... sort of irritating / needs code and DB fix
			- add/remove authors, and after save they are ordered by author.id, not order of addition (prob. needs book_author_link to have an auth_num)

#### SHOWSTOPPER:
BUG-19:		show unrated gets all books, looks like ORM is not joining as I expected -- I wonder if it relates to that SAWarning about book id being written in the wrong spot?
