[IMP] mrp*: make some MO's methods public

The `mrp.production` method `_pre_button_mark_done` will now be public
so it can be called since the web client.
This change is done in order to know if trying to mark as done a
production will return a wizard or not, which is needed in the new MRP
Display view since there is a delay before a MO is actually marked as
done and we don't want to see the wizard poping up after this delay but
before !

The method `_set_qty_producing` public is also public now because it's
called in `_onchange_producing` but saddly, the onchanges don't happen
in the MES view, so this way we can manually call it when needed.
