Log:
[r21832][Bug 666329] - Empty database after a little while

Separate the two uses of QofBook::dirty -- indicating that the book object
itself has been edited and indicating that some object in the dataset has
been changed -- into two separate variables with separate getters & setters.

The latter purpose, indicating that some object has been changed, is moved
to a new member variable of QofBook, session_dirty. Its new setter
qof_book_mark_session_dirty() and canceler qof_book_mark_session_saved()
are called only from the xml backend or gnc-autosave(). Its tester,
qof_book_session_not_saved() is used to check for the need to autosave
and to activate FileSaveAction.
