Subject: [PATCH] Bug 14598: (DB update) fix NULL itemtypes in statistics on
 'return' rows

This patch introduces an updatedatabase.pl entry that takes care of
updating existing statistics rows.

It does so by looping on the statistics rows, collecting itemnumber occurences
that are have NULL itemtypes.
It then chooses the right itemtype following what is proposed on bug 14651, and
then updates the rows in statistics using the calculated itemtype.
