[IMP] procurement: typo corrected
[FIX] sale: error occured when people invoiced a line of a sale order then tried to invoice the whole sale order. Now it raises an error because they are supposed to finish the billing process of that SO by line
[IMP] sale: small improvements in view
[IMP] sale_crm: lots of improvments
* made it use the onchange defined on sale.order.line
* corrected view that displayed error client side because of unknown args passed in context + added the note tab
* fix the sale.order.line creation in order to give also the price_unit and qty (and all other field of a sale.order.line, actually)
* removed unecessary attributes on sale.order.make.line
[IMP] sale_journal: created menu structure + removed widget selection not compatible with domain
[FIX] sale_layout: corrected rml (total net, taxes, total taxes included were missing + 'your reference' as wrongly filled
[IMP] sale_layout: removed the inheritance of tree view for lines and added a domain=[('layout_type','=','article')] on the menuitem sales \ billing \ lines to invoice
[IMP] project: duplicating a task doesn't copy the active field, which is also replaced by a function fields with store=true
