Process an uploaded EPUB file, returns BookVersion.
The book will be owned by the given ClusiveUser. If that argument is None, it will be
created as a public library book.
If book and sort_order arguments are given, they will be used to locate an existing Book and
possibly-existing BookVersion objects. For public library books, the title is used to
look for a matching Book. If there is no matching Book or BookVersion, they will be created.
If a matching BookVersion already exists it will be overwritten only if
the modification date in the EPUB metadata is newer.
This method will:
* unzip the file into the user media area
* find metadata
* create a manifest
* make a database record
It does NOT look for glossary words or parse the text content for vocabulary lists,
call scan_book for that.
Returns a tuple (bv, changed) of the BookVersion and a boolean value which will
be true if new book content was found. If "changed" is False, the bv is an existing
one that matches the given file and was not updated.
If there are any errors (such as a non-EPUB file), an exception will be raised.
