[22968] Bug #584869 net change line in general journal report broken

Do not show any totals in the General Journal report.

According to

http://www.accountingtools.com/general-journal
and
http://accountophobia.blogspot.de/2012/06/general-journal.html

it is not the idea of the General Journal to show totals but
only list transactions.

This patch makes use of the ledger-type? flag and suppresses
the output of the Net Changes accordingly.

By that, the General Journal will not show Totals, but the
Account Report still does.
