derive should set repub_state to 4 for non-microfilm book

[danh]

The derive process should set the repub state of a non-microfilm book
to 4 at the end of a successful derive.

This already happens from scribe2 books but not scribe1 books.

This is so that queries for scan lists at scribes can run faster.

[danh (danh-archive)]

Added a function nonMicrofilmBookSetRepubState4() to
petabox/deriver/inc/Deriver.inc which checks if an item is a book,
but not a microfilm book, and if so, modifies its repub_state to be 4.

This is in revision 1.135 of the Deriver.

(At first i tried combining it with the bookPostHack(), but rolling them
together would complicate the return logic of the bookPostHack(), so i made
it separate.)

Anybody please feel free to change this around or let me know if
it should be made more satisfactory in any way.
