Books in items structure isn't correct

$items_floor_field_list =~ s/booktype/booklang/g; #our booktype is mixed with theirs...

This comment in the import script is incorrect. We have our fields incorrectly labeled.

In 13th Floor and Lucy items, they have booktype which can be 0 (non-book) or 1 (book). In 13th Floor items, they have booklang (Lucy calls it bookunk) which is the language id to use in the book.

int32_t language;

In our books table, that is where we currently hold the language id.
