Update of /home/cvs/cvsroot/gnucash/src/engine
In directory www.linas.org:/tmp/cvs-serv5598/src/engine

Modified Files:
	BackendP.h gnc-book.c gnc-book.h kvp_doc.txt 
Log Message:
- Add new Backend method, counter(), which increments a named counter and
  returns the new value.
- Add gnc_book_get_counter() which implements the API and calls the
  counter() method in the backend if it exists.  If not, it stores the
  counters in the Book KVP Frame.
- Modify all the Business objects to use the new counter API.  Counter is
  gint64 so modify all the users to expect that.
