[IMP] modules version do not follow the OCA guideline

Created by: zaoral

module: user_story version: 2.6

This module version number do not match with the OCA guidelines. The version is 2.6 but should be 8.0.2.6.0

Change here https://github.com/Vauxoo/addons-vauxoo/blob/8.0/user_story/__openerp__.py#L28

Maybe another modules are in the same condition.
