This fixes an accounting issue where manually posted journal entries could create incorrect balancing entries when default taxes were set on accounts. Businesses get more accurate accounting records and fewer posting errors when entering journal items manually.

Hello,

this should fix the mentioned Problems in https://github.com/odoo/odoo/issues/1655 for master and 8.0:

"Journal Items - manual posting with Accounts containing default Taxes gives wrong results"

looking forward to your feedback as this is my first github pull request for odoo.

with kind regards,
Sven
