Also:
- removed onchange_partner_id() from 'project.project' model as
'pricelist_id' field does not exist in project nor in any inherit(s)
since its removal in 2008 by 07b1f0b9da
- removed 'type' field from _defaults dictionary of 'project.project'
model as it does not exists anymore, it used to be defined on
account.analytic.account
- removed on_change_template() from 'account.analytic.account' model as
it doesn't seem to be useful and/or called from any view
- overridden _default_get() for 'project.project' model to set default
value for 'use_tasks' field of inherits account.analytic.account
- created report/project_cumulative.py for model
project.task.history.cumulative that was in project.py
- moved project.project kanban view from project_dashboard.xml
to project_views.xml, which required moving some menuitems
as well so they are available while refering them in other files
